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?

Here is the screen shot of the "mtr" running from two servers:
Server1: Fibre optic line from Tata Communication
Server2: DSL line from Tata Communications
Source servers are located in Kolkata India
Target server is located in Fremont California.
The fiber optic cable has:
A. Higher ping time and
B. Higher standard deviation
compared to the DSl line.

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?

Assuming that one was to get a local office in a town, how would someone find building or area that had a high availbility of fiber nearby, but was not a datacenter? Are their fiber maps for each big city? Does anyone have fiber maps for Houston, Texas? I would be interested in seeing these maps if possible.

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 ?

Does anyone have any information on a company called BROOKS FIBER COMMUNICATIONS - TEXAS? They are showing up in a couple CO's on the telcodata.us website.
I think they might have been bought out, possibly by Verizon/MCI. If anyone can share any information about this company that would be great. Nothing seems to show up in google.

Me and my friend are looking to place a few servers for a soho (3 servers or so). We need advise as the incoming connectivity will be fiber so we need to know what do we need to receive that fiber, we opted to go for the catalyst 2950 for the switch but if there's a good fiber switch,
Fiber will be 10mbps.

Has anyone worked with the cable companies on internet connections for hosting? Eg. Comcast, TW.
I worked with a sales rep for Comcast a few years ago on a solution for our offices. He worked out a line that would give us 3+mbits up speed for less then the price of a T1.
It also included a dedicated line to our offices. Would using a cable line be a bad idea for a hosting connection?

I have had a few Colo and Dedicated servers but I have decided that the traffic I am getting on my sites warrants using a large setup so I have four servers that I need to colo to one site.
My major question is that when I go colo they generally only supply one Cat 5 cable and what is the best setup to have for a switch/router? Generally you get enough IP addresses to have one per server so my guess is that you can just plug the switch/router in and away you go?
I am going to have one server as a load balancer then two as the load balanced pair and then a database server.

Many of the VPS providers I've looked at don't back up the servers that house the VPSs and as such don't back up the VPSs either - have you considered what would happen should the VPS itself be erased (such as what happened to vaserv/fsckvps not too long ago)?

I know typically at least CAT5 cable is to be used for FE or Gig-E Ethernet links, but can CAT3 cable be used at short distances? I know there is little to none cost difference in the cable price, but I am only allowed to used the preinstalled cable at this location which is CAT3 which is what Verizon typically runs for telephone cables.

So we have 10 racks of mess in our custom colo cage. Each rack currently has 20+ servers, most with dual network interfaces hooked up, most racks with two switches and 3+ apc remote power strips per rack. Each rack is an APC 4 post unit [url]
We have no cable management trays and currently tie up cables with velco and zapstraps, trying to keep power cables to the left and cat5 cables to the right. Unfortunately, even with all our effort, it's really turning into a wall of cabling that is basically insulating each rack and causing a temperature issue (or the potential for one at least).
Even worse, we want to add in KVM over IP hooked up on nearly every server. While I see the great benefits of the KVM, I can't see how on earth we are going to make the cabling work out!

I have a Linux Server (CentOS 4.4) running, it has two network cards.
1. Onboard 100MBit (eth0), uses DHCP to obtain IP, this card is the only one that is able to connect to the internet.
IP: 192.168.1.13
Subnet: 255.255.255.0
Gateway: 192.168.1.1
Bcast: 192.168.1.255
2. PCI Gigabit card (eth1), uses static IP, and is connected to my Windows machines via a CROSSOVER cable.
IP: 192.168.2.2
Subnet: 255.255.255.0
Gateway: NONE
Bcast: 192.168.2.255
Before I installed the gigabit card all internet was working fine. However now i cannot even ping? here is some more info:

I just came across this listing for Corning Optical Fiber LEAF(R) on eBay [url]. I've never used optic fiber cables before and want to experiment with them for indoor and inter-floor(friend below) use. The listing says that the coating is CPC6, which is some kind of acrylic coating over the fiber.
My question is: Can the above cable be used without further sleeving or some other protection/covering over it? I read somewhere that the cable must be reinforced and covered with PVC jacket or something,
