When we get the servers up and running again, we have decided that Donations will last for two months. This is mainly due to us getting more servers, and Jake needs the money to keep everything up and running. Current donations will start from when the servers get back up, so if you have already donated you do not need to worry about it for two months until the expiry date.
I don't think this is unfair, as it's only £5 every two months if you want to keep your status. The status will be taken off of the Server only, not the site, so if your donation runs out in that time period you will still show up as donated on the site, but as a regular member on the server.
