Maybe iut was just my companies IT department slowing down my PC at a particular moment, but I was browsing around in ATP and leaving one area, when ATP paused for 8-12 seconds with a small browser or ATP message :
"waiting for google-analytics.com"
Maybe it's just me, and maybe just the network at work.
This is the first time it lasted long enough to read (and type) the message.
At least it was on FireFox and not IE7.
But if Google really is hanging up your site while it figures out what ads to push next, what a bummer!
