For a site that currently has an Alexa traffic ranking of 5, this is pretty dumb. It’s almost as bad as the sporadic errors on myspace. Site maintenance? Really? At 10:45am on a Tuesday? Come’on.. give me a break. Facebook is one of the busiest sites on the net and you disable my account for “a few hours” in the middle of the day? I’d expect they would be able to release code with a “flip of the switch”. If not, I’d expect downtime to be scheduled and during times of minimal traffic.
