more on SF outage
The story is evolving, as you'd expect. An excerpt from the latest update at the Chron is below. Nothing at this hour has appeared on 365main.com. But go there and take a look and decide if *your* colo has better stuff. http://www.365main.com/365_main_tour_2.html And now that we know this isn't enough . . . your move. fh PS I am not a customer of 365 Main or any colo for that matter. ---------------------- http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2007/07/24/BAG9NR67253.DTL&tsp1 The datacenter 365 Main -- which hosts a number of Internet sites, including Craigslist, Yelp and RedEnvelope -- also lost power, causing frustration among many Web surfers. Several of the sites posted messages to explain to their users that they were having difficulties, while others said they were undergoing scheduled maintenance or upgrades. After about 45 mintues, power to the datacenter was restored by back-up generators that remained in service until PG&E could confirm that its supply was stable. There was no immediate response from the facility as to why the generators were not turned on right after the blackout. Some of the sites, including Craigslist, remained down even after power was restored, as administrators ensured that data in the server hadn't been damaged, among other checks.
Once the final analysis of this event is provided, it is likely going to be due to a failure of one of the redundant systems to handle the event as designed due to a software or other low level failure. It's a very complex system designed to exceed anything in the region as far as redundancy goes, but as a result it's got a lot of moving parts, and like the space shuttle, can fail unexpectedly. You can bet engineering is scratching their head and calling in the vendors to figure out what went wrong. Last time this occurred it took weeks to pinpoint the root cause.
