Update: All done, thank you.
Due to a problem with yesterday's scheduled maintenance, we need another little spot of downtime.

During this time, the forum will probably remain up, but you'll be unable to login. Everything else, including the API, will be inaccessible.
If we get lucky, we'll only be down for 5-10 minutes, but in the past 20-30 minutes has proved more realistic.
Sorry for the inconvenience!
