Edit 2: Services are back up and running.
Edit: Due to a database error, we're doing this NOW.
I need to fix some stuff up on the server network tomorrow - so be aware that I'll likely be taking the server down for a couple of hours, likely starting at 1pm GMT.
I'm sorry for the inconvenience - hopefully it'll be quicker than that!
P.S. On 5.0.2, we're holding off for the moment, as we've seen a lot of bug reports. We'll likely wait for 5.0.3, depending on the length of time this might take - we have no ETA on that.
