RE: more on SF outage
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.
