I have to complain about this. It's rediculous how bad the PlayStation Network is at the moment. I purchased Warhawk for PlayStation 3 last weekend, and since then I have played it twice on a ranked server.
The Australian Warhawk Servers are always full, always. Then Sony released firmware 1.92 for the PS3 on Tuesday night. Since then the network has barely been working. So a combination of full servers and bad net code in the most recent update have made Warhawk the best waste of money I've had in some time.
