Problem:

Slack integration was not working at all, meaning that posts were not sent to the connected Slack channels.

Affected:

All customers who enabled Slack integration and made posts in the connected channels.

Root cause:

Network communication between two containers in the same pod begin to fail and never recovered on its own.
