G15 errors: We're currently experiencing intermittent issues with gateways getting into a bad state. Sometimes a gateway will stop letting traffic through, which means that certain people won't be able to reach the server (resulting in the G15 error.) Those bad gateways need to be restarted manually after a problem is identified. We've added additional logging to the Live environment that will help us diagnose the cause of these gateway collapses. We're trying to stay on top of these problems as best as our current resources allow, but we can look for a more permanent fix once the data comes in.
