I am not in any kind of hurry to buy or sell, I am just sitting on my coins and watching. It just seems that mtgox isn't doing anything to help themselves.
Upgrading their servers isn't enough to fix the problem.
"Cool down" means they're hoping that when they re-open there'll be less people panic buying/selling based on emotion and so they won't be overwhelmed by people stampeding to trade based on the slightest movement.
