It's easy to see that the Bitcoin market is under stress when there's rising overall activity and tighter oversight. However, it's now so hectic that the Mt. Gox exchange has trouble fulfilling even basic transactions -- and the institution is freezing US dollar withdrawals for two weeks to keep things in check. Mt. Gox's team will use the downtime to upgrade its trading system and (hopefully) address the heavy workload. Deposits and transfers in American currency should still be good to go. Let's just hope that Mt. Gox manages smoother transitions in the future -- after all, not everyone can afford to leave their money in limbo during a tech refresh.
