Issue Summary:



On July 29, 2019, at 7:23 a.m. PDT, we made a change that inadvertently caused some performance issues, including messages failing to send. Some customers had trouble accessing their Slack workspaces entirely. By 8:47 a.m. PDT, we identified the cause and reverted the change. The issue was fully resolved by 8:48 a.m. PDT.

We're pleased to report that we have the all clear, and all functionality is now restored. Thanks so much for bearing with us in the meantime.

Customers may be running into trouble accessing their Slack workspaces completely. We're actively looking into this and apologize for the interruption to your day.
