Hello — we’ve seen some issues early this afternoon.
I’m really sorry, they were my fault. I pushed some updates to one of our key servers that had tested fine locally and seemed innocuous enough.
However, once they were live they created a steadily escalating set of issues that, furthermore, rather obscured their immediate cause.
I’ve rolled those updates back, now, and everything has been behaving perfectly for the last 30-40 mins, so I think I can get on with investigating exactly why the updates created the issues they did.
Again, I’m really sorry if you were one of the people affected by the problems.
