Yep, I'm grousing about it here:

The fact of the matter is, SkypeWeb in vB 3.5.4 relies on reaching this external server. In my case, it's causing stalls on every page of every thread in my forum. I ultimately had to disable SkypeWeb functionality (which wasn't too difficult, luckily, since I'm still on 3.5.3.)
vBulletin should auto-disable SkypeWeb when that server is down, or at the very least, allow us to revert to the "old" way of doing things. Otherwise everytime that server goes down, our forums stop working properly.
Bad upgrade, bad!
