See that's what I thought too, except that:
1. I seems to get that via a server in the UK (looks like Ireland. Don't know why not somewhere int he States but ok)
2. It persists until the game is over, drops, and then will push me back on to it after starting a new match search. If it takes too long to find one locally this server starts to come up.
And yes it does affect my ping. Local dedicated servers give me ~7ms while this gives me a slightly laggy feeling ~30ms. The Brazilian one gives me ~130ms. Both show the same behavior of a local server + this odd one. Like I said, it's very weird and I've only had this start happening in the last couple of months or so.
Is there anything that indicate what this might be in the logs? I can keep an eye on them while playing and see what, if anything, shows up.
