We have found a potential issue with our servers relating to security. The chances of attack are miniscule but we have fixed the issue anyway. Our servers need to restart to make the change effective.
Normally we would wait to do this out of hours, but since we are talking about a potential security issue, we'd like to do that quickly.
Each server will be restarted in turn. There will be no loss of SchemeServe service, and you probably wont even notice, though its possible for slight performance hits while the sequence completes, which is why I'm adding a notice here.
Will all be complete by 12pm.
