From a site's admin:

bB was unfortunately hit by a hardware fault, our core machine is currently down and remote hands wasn't able to get it POSTing. I've got an FE going in to take a look on Monday, ideally they manage to get the machine back online, but if not, we'll have to proceed to DR and there's no telling when we'll be able to come back up.

So either the site comes back Monday 6/19, or you'll have to expect a significantly longer downtime, ~O(weeks).
