TDS Telecommunications said it had experienced a "double failure" on two diverse routes of its network that go through New York. One source of trouble stemmed from a third-party data center outage in New York, and a second problem concerned an AT&T cable issue. About 9,000 data customers in New Hampshire were affected by the problem, since fixed.
"It's interesting," said DeAnne Boegli, TDS spokeswoman, "even when you have two options going into opposite sides of the city, they both get impacted."
Earlier in the week, monitoring firm Renesys, said the hurricane had caused outages in 10% of the networks in New York.
"Silencing ten percent of the networks in the New York area is like taking out an entire country the size of Austria, in terms of impact on the global routing table," wrote Renesys CTO James Cowie, on a blog.
It's too early to write a post mortem. The lower Manhattan data centers aren't expecting utility power until Sunday or Monday. Until then, the anxiety level will remain above normal, as data centers rely on generators, fuel trucks and ingenuity.
