On September 29, 2020 from 3:57 a.m. to 6:12 a.m. PDT, some users encountered degraded performance and connectivity troubles within Slack.
A recent operating system upgrade didn't include the necessary network configuration, which limited the way our web infrastructure communicated with some of our servers. Some users then experienced slowness within Slack, such as when loading channels, as well as some requests failing altogether, such as messages failing to send. We resolved the issue by deploying a configuration change to some of our servers.
