SiteMeter is a popular web statistics tool, used by lots of bloggers, including the ones in Nick Denton’s Gawker network. I’ve used it myself in the past, but found that other solutions were more useful. Still, it has a lot of followers, so the recent downtime on S24, S45 and S48 numbered accounts is probably a big deal. SiteMeter hasn’t been able to restore the lost statistics during the downtime, which is said to be caused by an “extended power outage”. Obviously their power backup systems weren’t up to speed.
