UPDATE: Site’s online now and everything is heading back to normal.

Previously: A group of us are figuring out the best way to bring the site back online after an unexpected outage. Shouldn’t be that long, but once we bring it back up, a small number of users will notice some inconsistencies (e.g.,photo activity appearing on their "recent activity" page, but no new comments visible on the photo – that kind of thing). All these things will be fixed, and there is no need to re-upload or re-edit anything.
