Greenwood, SC | Level3 Outage
My Embarq DSL connection was down for about 2 hours due to the Level3 issues. I was pulling an IP address but had no outside connectivity. I was told the outage affected most, if not all of SC, NC, and VA Embarq customers. |

I told him that POS Linksys took down the web!

| AT&T Comm Outage
It now seems that AT&T wants to provide communications for critical utility services.

Watch any word wrap. The AT&T ad is the scariest damn thing I've read in a long time.  |

| Backup Power?
Does this at&t center have any sort of UPS protection, as well as backup generator power? I've seen almost every cell site down here in south florida has a backup generator attached to it. If this center was able to bring down that many wireless customers, and has no level of protection - it's a scary thought if this was a major black out as in 2003!! |

Re: whatever happened to redundancy?
said by RadioDoc :We'll wait for you to figure out how much of the Internet was actually "down" during this outage. Extra credit: Level 3 is one transport provider. How many others are there? Considering Level 3 is a Tier 1 provider, and it affected a wide area, I would imagine it affected many people, including other carriers (other Tier 1s that are peering, down to [especially single-homed] Tier 3s). That doesn't necessarily mean the effect was noticeable (in a crippling way) to all end-users, or wasn't countered by the other carriers.
Of course, the ones that are redundant would have just rerouted traffic (transit or peering) to another location, but that would have increased load on other circuits, possibly causing slow downs. Also assuming that the datacenter(s) in question weren't their only links in a chain to the rest of the world.
I skimmed the article and sub-articles, but was unable to find the cause of the Level 3 outage, only the AT&T one (also supported by Slashdot). I do find it interesting that a carrier as large as AT&T had power problems, usually backup power is N+1 or better. Are they really as reliable as they claim? Or only when the weather suits them?
Extra Credit: That depends on your definition of "transport provider". Assuming you mean a Tier 1, as Level 3 is, there are 7 others (AT&T, Verizon, Sprint, Qwest, Savvis, NTT, and Global Crossing). If you consider Tier 2s, there are likely thousands worldwide.

I did not lose connection to most of the sites people were not connecting with during that outage. But my ISP (at&t Yahoo! HSI) has their own peering agreements with Google, Microsoft, and Yahoo!, so all traffic to those sites leaves the local AT&T Internet Services (aka ATTIS) transit network directly for their respective transit networks; and never touches a Tier 1 network on the way:
There are currently eight recognized Tier 1 networks. If your ISP buys all transit to the Internet through just one of those Tier 1 networks, and that network goes down for any reason, you are hosed.
My ISP peers with at least two Tier 1 networks (AT&T Worldnet Services (ATTW; which is different from ATTIS), and Level 3), so I imagine that ATTW would pick up the load if Level 3 bombed.
There are also a number of other networks, at the Tier 2 level, which should, in a pinch, be able to route around a Tier 1 network gone south. More often than not, I never see a Tier 1 network in my routes; and about equally ATTW, or Level 3 when I do.

Re: AT&T Comm Outage
Scary How? Do you have any idea how an electrical grid works. It's called Supervisory Control And Data Acquisition (SCADA). Lets see, a data link is required to open and close breakers in substations not to mention required to see what breakers are open or closed. If electric dispatchers can't see or control their substations, how on earth do you expect and electrical grid to operate? Is this really what you want AT&T or any other public network involved with? I sure don't |

| Do you mean to tell me that AT&T (or any other public network provider) has no current involvement in the utilities now? I call BS. Maybe I'm missing something but as long as the infrastructure has sufficient redundancy capable of supplying the uptime deemed necessary by the utilities, why would it matter who provides, supports, and maintains the network?
Besides, AT&T's page that you linked to highlights wireless support for "field service/techs, metering, and management" and it hardly speaks to supporting the electrical grid.Innovative Solutions for Utilities
* Field Service Solutions. With field service automation, technicians can obtain work orders and customer site information in the field on their wireless ruggedized laptops or handheld devices. Following their on-site activities (service disconnect, collection, and repair), technicians can record activities and close work orders in real time.
* Advanced Metering Infrastructure (AMI) Solutions. With AT&T's wireless network and AMI solutions providers from our ecosystem, AMI is a reality whether your project requires IP addressable meters or uses a meshed network.
Benefits for CIO and IT Managers*
