The server will be down for a short time tomorrow at 2pm GMT for a script update. This downtime is necessary to ensure the update goes smoothly and everything works ok. The length of the downtime will depend on what goes wrong (hopefully nothing!).
Thanks.
PS
Before anyone asks, no, it's not the crews update.
The crews update has taken a bit of a back seat at the moment. I'm not sure when it will come. It's about 80% finished.
