Well I not only patched to 1.30 but also picked up SOU recently so I can't get in until you upgrade.
I did have a suggestion though. I assume (when Europe catches up) you intend to modify the mod with SOU, thus leaving anyone who does not have it behind. Maybe you should just save your non-SOU server and, providing there is demand for it host that one at times too, know what I mean? This way if people who are trying out NWN's for the first time (or also for those who simply don't want to upgrade yet) wanna play the IW mod you can set a hosting date for the 'non-SOU' version. Couldn't hurt to have the old mod still around anyway eh?
