We've discussed means of putting up messages during outages, but while an outage is happening, anybody who could put up a message is busy fixing the problem. We could start a blog for that purpose, I guess...
We were only down for about 137 minutes this time, though, which really isn't very long to remain in suspense. It's much easier for us to notify the admins of problems these days than it has been in the past, and that makes a big difference in the response times. The forum went down at roughly 10:50am eastern, we emailed Doug at 10:53, and he replied that he was on the case at 10:57.
