Redundant DNS Servers? How Do You Set Them Up
Apr 8, 2009Because of the attack on theplanet yesterday, my sites were down.
People are mentioning adding "redundant DNS servers" to protect against downtime in future attacks.. but I haven't found any info on how to set these up.
I also seen somebody post that the planet doesn't allow "zone transfers" so I'm a bit confused at how to proceed.
I just registered an account at [url] and I'm unsure on where to begin. Their FAQ is just a large photo.
My .com is registered at Godaddy. Do I edit records at godaddy to point to the server IP? Or do I have to edit records via WHM?
Is My Host Redundant
May 28, 2008I have a renewal bill for my hosting account, but I can't see if I have any domains in it and therefore not sure if I should cancel it or not. I am with bright-byte.
Can I do a domain tools reverse search or something on the domain so it can tell me which of my domains are with that host?

Host My Own DNS Servers
Jun 20, 2008I'm getting a VPS and I need to host my own DNS servers.
How many IPs do I need for this?
Is it easy to do since I know almost nothing?
The only thing I know is that I'll need a DNS provider, I know about everydns.net wich is free and DNSPark.com.
And about the IPs I'll be hosting 2 different sites, that means that I'll need 2 different IPs?
Do You Know Any Host That Offer RTO Servers
Mar 29, 2009I saw on Pacific Rack they have a section where they offer Rent To Own (RTO) servers. This is what I've been looking for and would like to know if any other host have this kind of offering?
From what I read from the site, RTO servers feature server financing over a set period of months, allowing a capital strapped customer from the initial large expense of purchasing a server. RTO server's are subscribed to as dedicated servers with part of your monthly payment going torwards the cost of the server. Once the set period of months has been reached, the server ownership is transferred to you. You then convert to a colocation plan, benefiting from asset ownership. Once you own the server, you can do what you wish with it, including having it shipped to you. (taken from PR website)
Redundant DNS
Oct 6, 2009I have been working on and designing a hosting company. Now setting up my names servers has came to a question. When I ran a previous business with a partner he only use Name Servers on 1 Machine in 1 location.
Now my question is my first server is going to be located in New Jersey, USA . So that is where My first set of DNS starts. With my previous partner I noticed most of the customers were based in Europe, Philippines, etc. Over seas. Now What I am asking is Will a VPS in a different location work for DNS Server. That way I can keep a lower budget till we get a few customers under out belt.
How To Host A Forum With Multiple Web Servers?
Jul 10, 2007I notice that some forums are run by multiple web servers.
They offer choices for visitors from different regions so that they can enjoy a better speed when browsing.
e.g. Visitors from USA use www1 , visitors from Europe use www2
My question is: how to synchronize the contents and files between different web servers?
For the dynamic content, one database server can be setup. So that all php scripts on different web servers can retrieve from the same database source.
But then, in a real-time forum, how to synchronize the files between the web servers? For example, one user from www1 uploads a file. This file will go to www1's filesystem. How to make this file appears in www2's filesytem?
I can think of 'rsync' every minute between servers. But still it's not real-time, and there may be problems if sychronication can't be finished within the minute.
Redundant Hosting ....
Aug 13, 2009I currently run spiderloop.com a SEO control panel designed for windows hosting accounts. The site and web service is hosted on our own server and works great, however I am concerned about redundancy and do not want to purchase a whole other server just to be fail safe. So I am going to purchase a shared hosting account to facilitate redundancy.
So here is the question.
How do I do it? How do I set up my current host to redirect to the new host when it goes down?
If the current host has problems how can I force the users browser to redirect to the redundant host? I simply don't understand.
Redundant Config
Mar 18, 2007I've decided to move from managed hosting to colocated hosting and I'm in a bit over my head as far designing the server configuration goes. I'm looking for assistance with setting up a fully redundant configuration with no SPOF (single point of failure).
The colo provider ensures full redundancy to the cabinet, terminating with two network drops from diverse bandwidth providers and HSRP. I need to eliminate all SPOFs inside the cabinet.
Some questions...
1) I'm thinking of using the Cisco 2960 Series switch as the in-cabinet distribution switch. I believe it supports HSRP. From my understanding, the switch will automatically failover from one uplink to the other in case of a network problem on one of the uplinks, and this will all be transparent to any servers connected to the switch. Is this correct?
2) However, this introduces the switch as SPOF. So, I believe what I need to do is ask the colo for a second pair of network drops and deploy a pair of 2960's. Then I would connect each server to both switches via separate NICs. Is this correct?
3) Finally, assuming I am on the right track here, I would like this to all be transparent and automatic with no human intervention required to recover from a switch failure. The servers will be running RHEL 4. How would I configure the network interfaces on the servers so that they can transparently use either (or both) of the switches? Is there some way to assign the same IP address to more than one interface? How does the OS keep from getting confused about where to send the traffic?
Thanks in advance for any insight. I would also be happy to hear recommendations for excellent network consultants that I could hire to design and implement this configuration for me.
Redundant Server
Sep 15, 2007I have two servers. One hosts about 55 small sites and the other does nothing.
Can I make use of the spare one to take over automatically if the main server fails for whatever reason?
I had been thinking of using Rsync to backup accounts / mail every 6 hours or so and then manually changing the nameservers on the domains in the event of server1 failing. Would that even work? Then I got thinking about it all being automatic.
Redundant VPS Solution
Apr 14, 2007I have a few VPS's, the main one has cPanel/WHM and runs all my sites / email / DNS and MySQL DB's. Heres a little info:
VPS1 - CentOS 4.4, cPanel/WHM, runs all domains (OpenVZ)
VPS2 - CentOS 4.4, Webmin, Slave DNS to VPS1 using Webmin cluster (OpenVZ)
VPS3 - CentOS 4.4, Webmin, Slave DNS to VPS1 using Webmin cluster (Xen)
However, if VPS1 fails for say 24 hours, im screwed!
So, my question is can I get some kind of redunadancy built in somewhere. For example if someone is trying to access my domain "mydomain.com" and the main VPS is down, then the request for the site would go to VPS2, or VPS3...
The same for the mail server, if some is sending mail to one of the domains on the VPS, and the main VPS was down, the mail would be sent to my other VPS's.
I just don not like the fact there is a single point of failure!
I do have WHM managed Weekly and Monthly backups of all cPanel accounts etc.
Redundant EMail Service
Jun 11, 2009We are a hosting company in Colombia, and we want start selling corporate email service.
The main idea is have two servers with redundance, I think this servers have to share the filesystem I don't know if using a scsi disk or just a network file system. We also want to have a good appliance for stop the SPAM, Im not so sure if we need to have redundance on it, its ideal but we are just starting the bussines and we dosn't have cliets yet.
Can anyone share their setup with us, and give us recomendations or tips?
Another option is, if someone know how to do that and have implemented this setup before and want to work $$ with us to implement that, please contact me to jbravo[at]colombiahosting.com.co
Redundant Network Cards
Aug 29, 2007to setup a Windows server that can support the failure of the switch that comes before it in the network diagram. The idea would be that if the 15A circuit the switch was on failed, or the switch just died, the server would still be online.
I already have two switches in spanning tree just before the server. Is there a way to assign a single IP to the server on both its network cards and connect each card to a different (spanning tree'd) switch?
Redundant Power Supply
Jul 30, 2007I'm upgrading my server again and now that we have 8 disks we need to upgrade our power supply (I was told).
But do I really need a redundant power supply Or can I just buy ONE 650 watt to upgrade?
These are my current server specs:
Quote:
2 X AMD opteron 270 dual core
2 X 2 GB kingston PC3200 DDR ram
2 X 1 GB kingston PC3200 DDR ram
(6 GB total)
8 X seagate cheetah 15k.5 SCSI 73.4 GB, U320, SCA in raid 10
1 X LSI megaraid 320-2x raid controller, dual channel
1 X Tyan thunder 8KSE (s2892) mobo
1 X 2 * 4 port chenbro scsi backplane (8 ports total)
2 X AMD CPU cooler
2 X 40X40X10 fans
(Currently 1 X zippy P2G-6510P, 2U, single power supply, 510 Watt)
1 X Sony FDD 1.44"
1 X chenbro RM311, 3U case with 8 hot swap bays
1 X LG DVD/CD-rom burner
Redundant Router Setup
Jun 5, 2007I'm in the process to setup a new service with an ISP with the following scenario and need your help.
I've got the rack (42U), servers and switches. Only routers has been left and here is that I need your help.
I have also 2 ports from the ISP where I can connect my routers. I need to get 2 router devices with auto sync feature in order to be able to setup a redundant plan in case that one of them goes down.
Those routers should have firewall features too in order to avoid setup iptables rules for each server. A basic DDoS protection is needed too.
I'm going to push around 100Mbit of traffic across the servers but that will happen after 3-4 months from the initial setup. In the first instance no more than 10-20Mbit will be used.
I heard a lot about Cisco but got no idea what model is the most suitable for my case. I will probably need a module for DDoS attacks and another one for advanced security IOS from what I read but it is not clear to me.
Www0 And Www1 How To Host A Site On Multiple Servers
Apr 21, 2008My forum is becoming more and more active and i would like to know how to setup a website on two servers. Ive seen many sites using www0.example.com and www1.example.com. Is this difficult to do?

Nov 5, 2008Looking for redundant setup, round robin?
I'm looking to make high availability setup, and wondering how many of you have made it so?
we are looking to multi-home the page with a round robin setup, using multiple VPSs/dedicated servers geographically different locations.
Right now i'm still looking at "stale" DNS setup, no automanagement of servers down. Is there a service/software which already offers automatic changes of zones for removing servers which are down, and adding them back when they get back online?
Do i need to custom tailor everything?

Jan 10, 2008I have a DB server, running mysql 64bit. I would like to add another server to the mix to build some kind of redundancy if the 1st one were to go down.
View 7 Replies View RelatedRedundant Apache (failover System)
Sep 22, 2009I currently own several servers: let's say sites on 3 of those servers rely on a website that sits on server 4
If server 4 goes offline, then servers 1 2 and 3 suffer a lack of usability.
The website on server 4 is very small and fast, but receives several hundred thousand visits a day
I figured it would be a good idea to replicate that website on each of my servers, but I'm unsure about how to set up a good redundancy system..
Using several nameservers doesn't work as expected (visitors are randomly sent to one of the nameservers, in no particular order)
Does Anyone Exceed 80% On Primary/redundant Circuits
Oct 18, 2009So the rule of thumb is if you have a 30A circuit to not exceed 80% or 24A.
If I buy a 30A circuit, I am assuming it is protected by a circuit breaker that is 30A, correct?
In *theory* we could run 29-30A all day and be fine.
So, I understand, the rule of 80% to be to the effect that "during startup, equipment uses more power ... or during runtime if it heats up, the fans go faster using more power" so it is safe to be at 24A in case you get spikes to 27-29A.
Is my reasoning correct?
Further, if you run primary/redundant circuits, is there really harm in running 13A on one circuit and 14A on the other.. and in the unlikely event of a failure, you are running 27A on one circuit (at 90% instead of 80%).
Any thoughts on this? Getting an extra 3A out of a 208V circuits is like putting in 3-4 more servers. If someone is doing this please let me know. I think it would work fine but i would like to know from the experts that do the colo stuff for a living what problems i could encounter, if any.

Dedicated Servers For Germany -- Good Providers? OK To Host In Amsterdam
Mar 9, 2008We need to get another dedicated server in Germany for a video application (so low latency and high-quality connectivity are crucial). Our current server is hosted with NetDirekt in Frankfurt -- our first year with them has been very good. However I want the next server located in a different city, for redundancy.
My considerations:
- English-speaking sales & support
- Highly reliable network
- Low latency to Germany users
Do you have any recommendations among the following short-list of providers?
Germany:
- plusserver.de
- probe-networks.de
- hosteurope.de
Amsterdam:
- eurovps.com
- leaseweb.com
Is Amsterdam a suitable location if I'm serving German end-users? Latency matters a lot... so if a German datacenter saves 20ms of latency, that's important.
Do you know of any other comparable providers -- especially ones that do not require a 12-month contract?
Setting Up Redundant Mirror/Mirroring Server
Jul 7, 2009I have a LAMP server running and would like to have the exact mirror running on another location. I would like to sync the web files and database in either real time (upon any update) or in delayed mode (x minutes after the update).
For MySQL, I believe replication can do the job unless anybody has better recommendation. What would you guys suggest for web files? Can I use different Linux flavor but maintain back the same LAMP version?
Is there any "online" 3rd party load balancing service that I could use to load balance the traffic to both servers?
How To Setup A Redundant Server For A Domain Name To Reduce Downtimes
Oct 29, 2008I have registered a domain using godaddy. I have hosted my site on a server of my shared hosting provider(lets call them X).Currently I have pointed mydomain.com to the server and it is up and running.Sometimes, I have experienced downtimes.
In order to solve this problem, I have hosted a clone of my site on another server from another hosting company(lets call them Y).
1. I want mydomain.com to point to Y when X is down
2. again point it to X when it is up.
My main aim is to have my site live with less downtime. The probability having both servers down is very less.
I dont know if it is technically feasible, just a thought out of dirty mind. I tried to google but was not able to find an answer specific to my problem.
Can anybody tell me how to achieve this through godaddy domain.
Added note, My site is not a commercial site and I cant afford large dedicated servers with clustering and failovers.

Name Servers Have Updated, But Site Still Points To Old Host! (was "")
Mar 22, 2007I updated my name servers to reflect my new web host two days ago. The name servers have updated, but the site is still pointing to the old host!
I emailed my host about this and they told me to email my registrar. The host says the domain is registered with the new name servers but these name servers are registered with IPs outside of their network. I'm confused and have never had this problem before when changing DNS.
Hardware: Db Servers, Web Servers, File Servers. Cpu, Ram, Disk
Jan 20, 2007I have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?

Power Supplies: Do Redundant Supplies Use More Power Than A Single Supply
Jul 27, 2009do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.
