What can be done with Heroku H99 error?

Question

Heroku production app (node.js) fails to start with H99 error for 1 hour.

According to documentation this error means 'heroku platform error' and is one of those that can't be fixed by app owner.

What can be done right now? Should I try fixing it somehow (rollback have already been done with no effect)

Answer 1

Just wait and/or email Heroku support
