BTCJam seems to be down - any ETA of when it's coming back up?

At around 5 PM US PDT, I lost access to BTCJam. When I reloaded the web page, I got a message saying that it was undergoing maintenance. Subsequent attempts lead me to a blank page. Does anyone know what's going on? Thanks (and I'm sorry if this is not the right forum, but my request to join the Facebook BTCJam Meetup group is still pending approval).

Update: I tried it again (5:24 PM US PDT) and I got the error message again.

I currently get a message saying it is down for maintenance.

Thanks (your message and my update "crossed the air")

Strange.

Nothing is said about it in their Tweet account.

Hope it is not about any security breach or another kind of attack.

It is back up.
