Not sure why they are down but it is a strange time of day (8:00 AM EDT) to be doing server upgrades isn’t it?

This graphic comes up on both the main Foursquare site and the mobile version.

Anyone heard anything about this?

Update at 8:26AM EDT: Found this tweet from about 14 hours ago:

So we’ll be down for some maintenance tomorrow morning from 7-8am EST. Hold your check-ins for that hour until we’re back. K thx bai about 14 hours ago via web Retweeted by 92 people


Seems they are running behind on their hour long maintenance.

Update at 8:43AM EDT: Looks like Foursquare is back up on all fronts!  So why do upgrades or planned maintenance periods always take longer than planned? :-)
