Some customers may have trouble loading new messages or connecting to Slack

Issue summary:
On August 19, 2020 at 5:30 p.m. PDT, we deployed a change in the connection process to some of our servers in the APAC region. A bug in the new code caused some of the API calls to be invalid, which resulted in connection problems for people. We rolled back the update and stabilized the affected servers. We returned to a healthy state by August 20, 2020 at 3:58 a.m. PDT.
