We're putting a ton of code live on FotoBilder right now. One of the included upgrades requires that we stop traffic to the site while it's done so that database state doesn't change. It should take roughtly 30 minutes. We'll have the site back up ASAP, and afterwards we should have some new toys for everyone to play with. : )
Thanks for your patience.
[Update: Still chuggin' along. Will update when finished.]
[Update: Done. We'll be fixing bugs as we find them.]
