I got about 5 times my usual traffic yesterday, which explains why there were some occasional slow-downs all across scienceblogs. I think the server held up fairly well, though, and I know the big guys here are planning some server upgrades to handle future growth.
Don’t worry, it’ll ease up. You can tell from the relatively small increase in page views vs. visits that most of these people zipped in to read one post and didn’t hang around. The new creationists trying to argue weakly in that thread have been mildly amusing, though.
