What's with "metrics.tetongravity.com?"

I ask because I am seeing a strange issue. When I go to a forum, pages load quickly and nicely. When I click on any thread, even a thread with minimal posts, my browser seems to be "searching" for metrics.tetongravity.com for a very long time (almost a full minute). The page loads quickly and I can see the content but the tab refresh keeps spinning and I have progress bar at the bottom stating it's "connecting to metrics.tetongravity.com" in Firefox and "Sending request..." in Chrome. These are both on mac with a very fast connection.

It causes no problems but something seems screwy you may want to check out.

thanks man, we'll keep an eye on it. Not happening on my puter, but who knows. Five days ago mine was hanging up loading 'avantlink'. That went away a couple hours later.

anybody else seeing this?
