On Friday one of our accounts went down. We've had accounts go down for review before, but never more than a day. This one's been down for four days now and nothing heard from Google. Traffic was pretty much solid each day, as far as I'm aware there were no spikes in impressions or cpc. It's not too big a deal because there wasn't anything too important running in it, but still, I've tried everything and nothing will show. Adwords support has been no help (as usual in these circumstances).
Anyone have any ideas? Is this a review, or a bigger problem?
