Carrier reliability and diversity

The air line reservation system Galileo had significant problems
earlier.

Excerpt from Reuters:
"The outage began about 8:30 p.m. Mountain Daylight Time on Wednesday
and lasted until 10:55 a.m. MDT on Thursday, said Beth Tennis, vice
present of enterprise networks for Quantitude, Galileo's Denver-based
networking subsidiary. It affected three of the four T-1 high-speed
data transmission lines supplied to Galileo by AT&T Corp., said
Beth Tennis"

4 T1's were down in Denver? Stop the world, I want off. :stuck_out_tongue:

You missed the bigger story about the AOL Instant Messanger outtage for a
large portion of the day (which I heard lots about from all my AIM loving
friends). Doubtless many thousands of network engineers were cut off from
their vital lines of communication.

Although I've found AT&T has the highest reliability of all the carriers
I've used. Redundant links from the same carrier frequently have a

Personally I've found AT&T to be a packet motel, packets go in but they
don't come out... To each their own...

Today was the second multi-hour outage in the past week of AIM
that i'm aware of.

Quick everyone install MSN for redundancy.

The service interruption was apparently a result of a major regional power failure in Northern Virginia. I'm curious whether it was AOL or their providers who suffered from the power failure. I would expect AOL would have back-up power.

Something's fishy about this.

I'm in Northern Virginia (Vienna), not 15 miles from AOL's facilities
(in Reston and Dulles). I experienced no power outage that day. So if
there was a failure, it was certainly not "major regional".

During the outage, the AIM client would successfully connect, but would
abort with a database error trying to validate passwords. Sounds more
like a servier failure to me. (Although to be fair, my first test was
less than 30 minutes before the service came back, so I may have been
seeing their reboot sequence.)
