One general note - now that I work in a hospital, I have to keep my mobile turned off while I'm in the building (i.e. 9-5). So, if I had arrived on time this morning, you wouldn't have been able to get hold of me, so please don't panic and think the worst in a case like that.
Anyway, it looks like most of the people I know have reported that they're safe, which is good to know.
