We make sure that all your data is nice and safe. When we see a potential security risk therefore, we need to take action to mitigate that risk. As a result of this ongoing monitoring, We'll need to restart each of our servers.
There is unlikely to be any downtime, as we will start and stop one server at a time, but there maybe a minute or two around 2200 BST (GMT+1) tonight.
Please tell our obsessive support people if you encounter an issue.
