I'm looking over the logs and there is nothing to indicate that there were wires switched (meaning, you were the only one logging in that minute). I'm assuming this hasn't happened before. I haven't recently pushed out any changes that would cause this to happen. Well, if it happens again, let me know.
Actually, this has been happening to me since the last upgrade. But it only happens when I'm using IE7 (work PC). I need to keep refreshing several times before it loads properly. Works fine if I'm using Chrome though.
