Fiber Optic Cable Down - No Back-up

Jun 26, 2007

I put this in the co-location section since I am co-locating a server that I host a few Websites on. The server is located in the Pacfic Northwest at a hosting company out there. As you may know, this is a "more remote" area of the United States.

Today, the company lost all Internet access when a Fiber optic cable went down. Not only was my stufff down but the entire hosting company was down. In 10 years of doing Internet development, I have never seen this happen to any hosting company I have worked with no matter how good or bad they were. On top of that, it happened one time last year as well.

According to my co-location provider, the problem happened a long way up stream. SO far that the lines cannot be backed up. Is this true? Could a fiber optic cable fail at some point where it cannot be switched over to another line?

I don't know if I should I believe that or not. It would seem to me that it is a matter of money and they may not have a back-up system in place if the pipe goes down. Is it possible? Who's fault is it?

Shared Dedi Lines Performance At Night Times

Sep 30, 2008

My business is on the other side of the world and peak time starts at midnight in America time. I am planning to buy 100Mbps shared servers with FDCServers. I am wondering if the time of the day makes a huge difference for a shared 100Mbps line.

Burstable Lines

Mar 20, 2008

if a provider provides me a 1Mbps AIMS dedicated line for my dedicated server, is it possible for him to make it burstable to 1.5Mbps? i thought when i get a dedicated line i would be able to get max 1Mbps only? How is it possible that it can be burstable? Does that mean its not dedicated, instead shared?

Is This Possible Using Voice/voip Lines?

Sep 26, 2006

I currently have a dialup isp. We use a couple of wholesale dialup service providers to provide service to our users across the nation. I would like to provide my own dialup services across the nation if the cost is justible.

Here is what I want to do:

1. Buy a remote access server (RAS) with hundreds of modems in it. The RAS will have multiple T1/PRI/T3 interface cards in it depending on which one I get.

2.Place the RAS in a Houston, TX datacenter.

3. Get voice services from a carrier that can deliever multiple T1/PRI lines (or a T3). I would want a local DID or phone number in hundredes of locations across the nation. When a number is called, it would be rerouted back to the Houston, TX PRI/T1/T3 connections WITHOUT ANY LONG DISTANCE CHARGES.

Is this possible without paying an arm and a leg for it? Can anyone give me any recommendations besides stay with a wholesale dialup provider.

Getting A T3 To Our Office

Jul 25, 2008

I've noticed on a T3 quote site that regardless of T3 speed, they seem to give you the same local loop connection (as it costs the same for each one). [url]It shows some of my information but I don't really mind (come get me! ). Notice that the local loop for T3 whether its 5 mbits or 45 mbits is ~1800 a month. Is that really what a local loop rated for T3 speeds costs?

I am in the bay area, in pleasanton specifically. It would be awesome to get a local loop to a datacenter and then pickup some bandwidth cheap from a provider. Does anyone have experience with local loops, and know their general price range and availability etc? I'd rather probe around here and be prepared before I go and give various providers a ring. in fremont is about 14.7 miles from the office, and MPT in san jose is about 30 miles away from us.

Going Colo In My Own Office With T1

Aug 10, 2007

I am located in Japan and presently am renting a dedicated windows 2003 server hosted in the US. However, most of my sites (about ten) cater to the local Japanese market. When I do a ping or traceroute to my server in the U.S. and compare it with same for servers in Japan, there is a world of difference.

8 hops in Japan as compared to 18 to the U.S. server. The hops in Japan are about 13 ms but the hops within the U.S. are 130 to 200ms from my location.

Based on this information, I would assume I would be better off having a server physically located here in Japan.

If I were running Linux, I would have no problems finding a good plan but I run Windows 2003 (all my sites are in ASP) and there isn't that much avaialble here. I got some quotes and even though the server rentals are reasonable, they kill you on options. Also, for some reason the plans here do not have additional IP's available as an option.

Backups are so high that they tell you to get two servers (nonsense).

I have also looked into colo in Japan. Most want you to rent a full rack. I found one that wanted $400 for 1/4 rack but then I would have to pay for a line on top of it.

The cost of bringing in a T1 line into my office is $275/mt which I think is reasonable (considering what stuff costs in Japan). My sites are not high traffic so a T1 line is probably enough. There is also 1GB optical fiber for the consumer market but I would think the T1 would be more reliable.

I realize there are those that insist that a server be located in a data center but power outings do not happen that often here. The office is located on the 5th floor of an office building.

Apache :: How To Detect Wamp And Ignore Some HTAccess Lines

May 12, 2013

My linux host requires a few lines of codes in my .htaccess file to properly run my site.

However, these few lines of codes are not supported by my local Wamp on Win7.

Is there a way to add a "If Wamp Then not run these lines" in my htaccess file

So that I don't have to manually change the .htaccess file before upload/downloading the site between the two systems?

Dark Fiber

Has anyone looked into getting dark fiber verse going direct with a transport provider? How much does dark fiber cost compared to say a Gig-E transport line? What kind of equipment is needed on each end of the fiber, and how much does this equipment cost? At what point does a provider look for dark fiber verse getting transport for a Lit provider?

Using CoLocation Connection At Branch Office

May 14, 2009

We have co-location space at a local San Diego data center with a 100mbps connection. We are looking for a faster internet connection at our office (currently just have DSL with is 1.5mbps down, 768kbps up) which is literally 2 miles away from the data center. I may be completely offbase and wrong here, but is there way we can setup a VPN connection or direct Point-to-Point connection between our office and our shared cabinet, and then utilize the internet connection and bandwidth provided by our shared cabinet for our office?

If this is possible, I would assume we would need special hardware, which is fine, just need details on how this works. Currently we have a SonicWall TZ180 at our shared cabinet and a Hotbrick SoHo 401W at the office.

Removing Fiber By Cutting It

Jun 23, 2009

We have a large amount of multimode fiber coiled up under our raised floor that needs to be removed. The end that remains intact is running to a SAN cabinet that is very densely populated and our vendor has suggested cutting the fiber to make it easier to remove without disturbing the remaining active fiber.

Does anyone have any experience cutting fiber in a data center environment ?

Are glass fragments or any other debris a concern ?

JaguarPC Performance VS. LiquidWeb Performance

Jul 13, 2007

I am using dreamhost host 3 of my web sites and 1 blog. Dreamhost is great, offers alot space and bandwidth.

but I think they are oversellling their space, sometimes it gets really slow. (overselling ? ok, I dont really know, but sometimes its really slow, and most my asian readers said need to refresh to load the page. I am wondering if theres a way to check if they are overselling or not.)

I am thinking about buying vps, even tho, I still got 5 month left with dreamhost.

I found 2 vps companies are highly recommanded on this forum, JaguarPC and LiquidWeb.

theres already a post compared both companies in terms of price and service. I say I will pick JagarPc, cuz, its basic plan just 20 USD, and htey got promotion now, its even cheaper. and basic Liquidweb vps plan is 60 bucks.

I am wondering why Jagarpc is so cheap , are they overselling? how can we check if they are overselling.

I found a few posts saying how good jaguarPc is. and they are not overselling, but those members just signed up this month, and only have 1-3 posts. I cannot really trust those new members.

Can someone share their experience with JaguarPC? compare JaguarPc performance and liquidweb performance. antoher question is switch from dreamhost to JaguarPC basic vPS plan, will performance gets better?

last question: VPS account allows 3 IP, 3ip = 3 domains? if not, how many domains can I have?

I've read several posts that explain what mime types to add, and I've found the spot where I need to enter them. The part I'm not sure about is whether the custom mime types field is an addition to the current mime types or a replacement list. Does that field just needs the new mime types or a full list?
