Different providers have exactly the same problem so issue is not related to temporary network issues or provider dedicated reasons. Network monitoring doesn't show any unusual things, also other services are running fine in the same network. Please suggest us how to debug / investigate such behaviour. Unfortunately nothing useful can be found in logs that could provide us better understanding of a root cause.

Interesting to note that it happens during the meetings in the morning only... @bgrozev, could you give a hint how we can find the root of the issue? Thank you
