I encountered an Error H99 (Platform error) on Heroku that made Heroku unusable.

Looking at the official Heroku site, it says “H99 is the only error that is caused by the Heroku platform.” Since H99 is caused by the Heroku platform, there’s no solution and you just have to wait for Heroku’s response.
H99 - Platform error This indicates an internal error in the Heroku platform. Unlike all of the other errors which will require action from you to correct, this one does not require action from you. Try again in a minute, or check the status site.2010-10-06T21:51:07-07:00 heroku[router]: Error H99 (Platform error) -> GET myapp.heroku.com/ web=none queue=0 wait=0ms service=0ms bytes=0 2010-10-06T21:51:07-07:00 heroku[nginx]: GET / HTTP/1.1 | 75.36.147.245 | 8132 | http | 503
You can check Heroku’s incident status/resolution status at the following site:
By the way, in my case, it was resolved in about 30 minutes.
That’s all from the Gemba.
