Update: Downtime this morning / Search down
Apologies for the downtime, I just found out when it happened. A disk problem meant the server was taken offline for a couple of hours for a rebuild.
Thanks for your patience and apologies again.
The MT search function is being temporarily removed to allow the hosting team to monitor the true function of the server. This is because the MT system is rubbish and hogs the CPU usage on various tasks.
In the meantime use the Yahoo search on the HUB page or the Google search as shown on the sidebar - note that the Yahoo search actually returns more results for some reason.
