*SIGH* - Server on it's last legs...
I've been fighting with one of our webservers for most of the afternoon, and slowly moving all of the sites from it on to a different machine, as it appears to be dying entirely. Hopefully we should have the remaining sites over there tommorow morning, then there's just the waiting till everyone has confirmed that they all work.
Many thanks to Dave who was also working till 6pm, I finished about 30 mins ago for the day, having had one real break of 30 mins, and a 20 min drive since ~ 3.30pm when I got to the server room to fit the other machine with a new disk to take the sites.
And now, I think I shall consider sleeping.
