Massive power outage in SF's Soma district takes many websites offline

Scott Beale says,

6 back-to-back power outages hit the SOMA neighborhood of San Francisco Tuesday afternoon causing major havoc with popular web services. 365 Main is down, along with craigslist, Netflix, Technorati and SixApart.

I was poking around on 365 Main's website and found this press release ("REDENVELOPE REPORTS TWO YEARS OF CONTINUOUS UPTIME
AT 365 MAIN'S SAN FRANCISCO DATA CENTER"). Take a look at the date :)

AP is reporting that it appears Netflix was not effected by the power outage.

Update: sounds like the incident was caused by some sort of weird explosion that led to a big power company outage: Link.
