The incredible part about this is because their backend is all TCP/IP they were literally exhausting the ports by leaving all 65k of them in TIME_WAIT, and the workaround was to start randomizing the localhost address to give them another trillion ports or so.
This is a pretty interesting solution. I could see how this could useful for certain kinds of problems (as part of a ddos attack mitigation for example).

I mean, it's one GetPostRecord, Michael. What could it cost? 1 trillion ports?
