it looks like FDC is taking more pain than usual in terms of network upgrade, i see the network seems unstable till 5am and even now the sessions are getting lost, once in a while like once a hr, anyway this is not the reason i am writing this, but when did comcast become transit provider, i did a trace to UK for example and i see trace going through comcast and then hopping onto tiscali/level3, it looks to me like, comcast could be trying to even out (1:1) it;s carriers so that they get all inbound for free sort of and it;s upstream selling as a transit make money there. sort of, just a surprise to me at this point

ive got a one of my personal sites - (a fairly mysql heavy chat community that works on mobile phones aswell) and its running on a cheap dedicated server
the specs of the server at the moment are -
celeron 2.0GHz 512mb ram 120gb ide disk 1500gb bandwidth linux centos 4 no control panel
now i never come close to using my bandwidth so thats fine. but ive noticed when i had around 30 members online last night the server load spiked at about 3.5 so im wondering if anyone can suggest what would be the best thing to upgrade to reduce load.
im currently running apache serving the dynamic files and lighttpd hosting images on a different port. using php 4.4.7 with eaccellerator. mod_gzip is enabled in apache due to a need to reduce the size of pages as much as possible.
BURSTNET Network Maintenance Advisory - Saturday, September 20th, 2008 - 2AM-4AM EST WINDOW
BurstNET™ Network Engineering will be performing maintenance in our Scranton facility during the hours of 2AM and 4AM EST on Saturday, September 20th, 2008. At this time, BurstNET™ Network Engineering will be performing a significant upgrade/replacement of our existing network infrastructure. This upgrade will involve removing/replacing our older/out-dated core Cisco™ GSR & Extreme Summit™ routing/switching equipment, with newer state-of-the-art Cisco™ 6500-series routing/switching equipment, and implementing a new network design---allowing for easier upgrade, higher fault-tolerance, additional capacity, and extra redundancy.
This maintenance will be service affecting, however, we expect the overall network downtime to be 30 minutes or less, during the 2-hour maintenance window, with the majority of that occurring at the start of the work...as equipment and cabling is changed. There will also be momentary periods of higher than normal latency while circuits are re-routed, BGP updated/reloaded, and cabling switched, throughout the 2-hour maintenance window. Proper planning, configuration, and testing has been completed in advance of this maintenance period, in order to minimize as much as possible the overall time that will be service affecting.
This maintenance is necessary in order for further growth of the BurstNET™ network, as well as to implement additional redundancy into the network. This should also help resolve any latency and packet loss issues our clientele may have been experiencing in recent weeks. BurstNET™ has recently hired new Network Engineering staff, and this is the first step in several upgrades/modifications they will be making to the BurstNET™ network over the next 60-90 days, to expand reliability, increase capacity, install further redundancy, and increase performance network-wide.
We thank you for your patience and understanding with this necessary maintenance, as well as for your continued business!
Sounds like a pretty major upgrade (they've been upgrading a lot recently). Here's to more uptime and redundancy at BurstNET!
Lastly, a quick point to the army of Burst-haters out there: go check outages, BurstNET has had two great months for us (99.9%+ uptime). Stop hating .
We're having a meeting today with Comcast about letting them move fiber into our facility. Please do not post experiences with Comcast CABLE. I want to know your experience as other datacenters and hosts with Comcast Fiber. What do you know about their fiber and what is your experience with them in both standalone and BGP?
Reliability, latency, peering quality, etc. We are in the Houston area, where so far I have heard they are pretty good with most I have talked to, and a few negatives. At what level would you use their connection?
I have Comcast Business PRO Internet service for work purposes. I've got two web/dns servers and two mail servers, each having their own IP. These are all fine.
There had been a couple situations in the past where I would receive a "Relaying Denied" message from my PINE when sending mail out. At examination of the maillog, It's essentially telling me that these messages are being generated because of the lack of reverse DNS.
xxx.xxx.xxx.xxx-Oregon.hfc.comcastbusiness.net., instead of my.domain.com.
I did a couple searches on Google, and read somewhere that Comcast is unwilling to create rDNS entries, but they've not specified, so far, whether they subscribe to PRO or residential service.
Before I spend 90 minutes on the phone with Comcast, I thought I'd see if anybody here has been successful with rDNS and Comcast PRO before. It seems to me that by denying this, it defeats the purpose of the "dedicated" service that I signed up with ...
On used equipment (for example, 6509s), is there any possibility of getting IOS upgrades from Cisco? Is there any sort of re-certification process? My only concern with used equipment is that often times the firmware is years old.
What are the benefits of moving to faster uplink speeds? I'm considering upgrading from 10 to 100 Mbps. Does it only mean being able to send information faster or are response times improved as well?
I've decided to move from my current provider (which I have praised many times on this forum before) because I'm just not getting the service I expect.
I'm specifically interested in a provider who is able to upgrade a VPS quickly, efficiently and on time, with no excuses and without "forgetting" things.
If you have experienced more than one upgrade with a provider which has been handled exceptionally well, please point me in the right direction.
I am a host reseller and the parent company is upgrading their servers to PHP5. This may break some of my clients' sites (OSCommerce, Zen). Should we fix those sites for free or should my clients pay for the upgrade?
Are there any co-location companies in California (preferably northern) that have a peering agreement directly with Comcast?
Not sure if it's peering or transit I should be asking about. Basically I'm trying to get the best path I can afford to Comcast customers in California.
I have a business class comcast account and have been able to host multiple sites on my server but ive recently read strange things about comcast's regulations towards this.
there really arent any alternatives in my area for a connection and i have multiple accounts right now. has anyone had any bad experiences in this situation?

For some reason... No one with a Comcast.net email address can email us..
Always the Rejected Email comes back with This message:
============================================================== A message (from <yyyyyyy@comcast.net>) was received at 29 Mar 2007 3:15:15 +0000.
The following addresses had delivery problems:

I have used "yyyyyyy" only to alter the email address for privacy..
I was wondering how I would go about ensuring my kernel is up to date on my vps. I am running centos and I have cpanel, so I am not sure if there is anything special that has to be done or avoided when running cpanel.
I find it very interesting that the major ISPs in and around Portland Oregon apparently do not peer with anyone in the region. For low latency you're better off choosing a provider in Seattle or San Jose as traffic always seems to be routed there and back anyways.
Why is this? Is it simply not worth their effort to setup the peering connections because most traffic will be hosted outside the region anyways?
I've recently gotten a new dedicated server and am in a bit of a bind because all emails to Comcast are blocked. I have verified that the IP is not on any RBL I can find but it does appear on the Trend Micro DUL list. This is a list that appears to not be maintained but which the wingnuts at Comcast are using. Emails to the maintainer of the list or to Comcast are auto-responded to and promptly ignored.
I'm at wits end (admittedly, not a long journey) with this. As a small provider I guess I just don't count but it is annoying as hell that there is no way to get these folks to listen. Every legitimate RBL on the planet has someone to help with issues but Trend Micro appears to not. And Comcast doesn't care about their customers getting legitimate email. Actually, I guess they just don't care period.
Has anyone else experienced this and, if so, were you able to figure out what magical incantation it takes to get through to a human who cares?
I just read this on their forums.Softlayer is pleased to announce that we have turned up a private 10G peer with Comcast in Dallas. This will bring our total capacity in Dallas to 70Gs.
Dallas, TX (dal01) - 70Gs Verio - 20G (2x 10G) Level3 - 10G Savvis - 10G Global Crossing - 10G Internap - 10G Comcast - 10G private peering Which other providers have this?
It appears Comcast is now blocking port 25. As a result, I can't sent outbound email via my dedicated server. They had me change to port 587 for my comast email account, but that doesn't solve my not being able to send outbound from my dedicated server.
Is there anythighn I can do (like change the post my mail server uses to 587) so that I can send outbound mail from my server with outlook (over Comcast connection) or am I just stuck now with using web mail?
Simple... new Plesk 12 includes this fancy feature to tell me which Wordpress plugins and themes need updating (because I obviously can't do this myself). But maybe I don't want to update some plugins (because they've been customized and changed)... how do I....
STOP Plesk 12 from sending me Wordpress update notification emails EVERY DAY!???? The auto-update is off... and EVERY day is sends me (and all of those clients) an ugly email about their Wordpress installations. How do I turn this OFF?
Okay, I have been trying to get a VPN network setup here between our DC and our office for weeks now and have not been sucessful.
Here is our goals:
-use 10.x.x.x/255.0.0.0 as a local backend network at our DC -be able to assign a 10.x.x.x address at the office to all workstations and be able to access any of the local machines at the DC -we have a asterisk server that we use and want to run that on the same network, asterisk box at the DC, phones at the office
We are wanting to impliment this for allot of security procedures and for ease.
But I also want to be able to have this like at my house so I can still be on the VPN. I want to have my house, office and DC always connected and then setup remote ability too to dial in via VPN.
What would be the best way to accomplish.
I have already tried having a few Linksys RV082 and WRV54G but the remote and local networks must be different networks, so this will not work here.
Does anybody know how can I determine which of the IPs within the network are used or not. I know that this can be archived by pinging each of the ips but there are 256 (192.168.1.0 - 192.168.1.255). I am using CentOS 5.
I bought another dedicated server yesterday and it was bought online same day. It was working fine yesterday during a few site transfers but now it would appear that I am losing network packets.
I have done a traceroute and ping tests and attached are the results. Please can anyone help. I think the problem is to do with NTT's network rather than server problems but please could someone else ping from their location to confirm this.
I have some VPS with Knownhost and i use it for hosting purposes.
First, I'm not from USA.
Here in my country we have several ISP but one of them ( i guess the biggest one ) is having problems with their link that connects to another countries ( including USA ).
Many of my customers that uses this ISP complains about their site being down and also slow download speeds ( 10kb/s when they usually download at 200kb/s ). When they run a traceroute i see that the problem is related to the ISP.
I have already contacted the ISP but they doesn't seen to "care" about their clients and i guess they won't solve this in a near future.
My question is if there is a way to solve this problem on my own?
I was thinking about getting a link with another ISP ( the one that really works ) with static IP and route this to Knownhost VPS. I know that this isn't a cheap solution but is it possible?
To make it simple, I am having some bays with dedicated servers. We offer 2 possibilities for bandwidth traffic: per Giga, or per MBit/s but I am having some problems. We currently use the router of our ISP better than buying a cheap low quality router.
- How can I know how much bandwidth does use on customer and how to limit if I have no access to the router ?
- How can I limit my customer from using free IP on the same block than he is ? We do configure server with IP and the same subnet, gateway and broadcast, so one customer could use free IP just so, and I would not even be able to know who is doing.
