I just had to restart my apps in the Frankfurt region as they were not reachable from the internet. Seemed to happen around 10:35 UTC.
As an example, I have an app with two instances. About 30 minutes after restarting the apps, one of the instances of reported critical again. Just now while writing this post, the other one also became unavailable.
Are there ongoing issues with the Frankfurt region? We had the same type of issue a couple of weeks ago, where we also had to restart the apps in order to get them working again. I couldn’t see any issues on the status page now, but something must be wrong.
Edit: since posting this, I am seeing timeouts in the logs again, and one of the nodes has gone critical
