Grading Telco & ISPs During the Blackout of 2003?

alt_cognito asks: "Our company runs natural gas generators here in Novi MI and when the power went out we didn't miss a beat. Nine hours later, our telco blinked and our T1 service went down despite the lines being run to different locations and ISPs (UUNet, LDMI). Service did not return until power had returned to the upstream offices. I was under the impression that these locations would be run by similar power generation. How did your telco/ISP perform?"
