I thought i'd post this here because it's been done a few times in the last week or so. If there is a short 5 minute period of forum downtime, accompanied by an SQL error or a 'page cannot be displayed' message, this is due to me rebooting the server after updating something.
This is normal and the server will always automatically restart all essential services after a few minutes. It has been happening more often recently because i have been trying to iron out a couple of problems with certain parts of the server, and a reboot is required each time something is changed.
I should have this issue fixed within the next day or so.
