Sudden delay in loading of startpage

[Sparkiller]

Over night a weird problem appeared in my vb-board. There is a sudden delay (about 20 seconds) when one tries to access the forum homepage ( http://www.projektstarwars.de/forum/ ), while on ALL subpages, and the portal-page, it works perfectly.

Yesterday all still worked fine and there have been no changes. Is it somehow possible to see what the board is trying to access at the same moment this delay is happening?

(pls excuse my english!)

PS: I already tried removing the nedstat-counter, but without success.

Have you installed any hacks? If so try reuploading the original default vBulletin files (make a backup of your old ones).
