It now appears our system came under DDoS attack as a result of "hacktivist" vigilante activity against a particular merchant. We have now suspended that merchant's account for violating our Terms of Service, which should lift the blockade of traffic to our servers by the time you read this. The security of our system was never at any risk; it was basically the Web equivalent of slamming your phone lines with so many prank calls that nobody else can get through. Thanks to everyone for your patience, with our apologies for the inconvenience.
