Oh what fun.
When I got up this morning the office machines were working as usual. By the time I arrived at work, all electricity to the building had been turned off because of a burst water pipe. It came back on at about 10:45 but they've decided to do electrical tests on the equipment in the machine room while it's turned off so it will take a fair while yet for the network to stabilise.
So I'm just exploring the OUCS help centre/terminal room, which seems to have been completely rejigged since I was last here (wot no vt220s?).
