Production App Outage. "H20 - App boot timeout"

Question

Our production app is facing a serious Outage with H20 - App boot timeout error logged.

Evidence strongly points to a heroku platform issue. We need some fast support.

Answer 1

Just encountered this. I'm not sure what caused it but "heroku ps:restart" seemed to fix it.

Answer 2

After several attempts "heroku ps:restart" solved this issue with few minutes of downtime. It didn't help when I tried 'heroku restart' alone.
