I have had better starts to a week than the 2:50am call on Monday. A hardware failure had forced my company to switch to their backup database server. The timing put it right in the middle of the UK day, so there was quite a lot of work to do; never easy under time pressure and doubly difficult when one is mostly asleep. I got back to bed a little before 5:30am, which gave me a couple of hours of rest. The only plus side was that I was moving to a different office, in the same building, so the fact that I felt like a zombie was not as great a drawback as it would be on a regular day.
