weblog list caching troubles?

interestingly, I just updated my weblog at ho.antville.org at 23:45, but even by now (23:55) it doesnt show up in the main list on www.antville.org (other recently modified do so though). When browsing through the complete list (somewhere at start=700) you'll find it, but there it's listed as last updated 20:49 - this is the time of the second latest entry on this weblog. caching troubles? any thoughts?
