Hi Snowman, sorry for not getting back and updating this thread.
I'm not sure if local issues could have been to blame - myself and another person both could not access the site from different ISPs in the UK (BT and AOL). I presume as it came at the same time as the server reboot that it had either gone unnoticed for a while or taken a long time to be booted back into a useable state. This was documented on your support site after the event (server was Perisher).
Despite that, server speed has been great
