Update: Foursquare is back! A report on what happen will be shown tomorrow, according to Foursquare on Twitter.

While the sign at Foursquare is saying Server upgrading, Foursquare on Twitter is saying Server Overloaded and that was 5 hours ago (from this post as I am writing). Can anyone let me know when it is up 🙂 ?
