We’re going to try to release another beta of CityDesk today.

At the same time, we’re shifting stuff from an older server to a spiffy new one. (Is that asking for trouble, or what?) While that happens, the discussion groups may be a little flaky.

I hate the way that when I change a server’s IP address, even though our TTL is set to 15 minutes, people are still using the old IP address almost a week later. Why is that?
