Trouble connecting to Slack

Issue summary:
On March 22, 2021 from around 9:01 a.m. to 9:22 a.m. PDT, a small number of users encountered trouble in Slack, such as messages failing to send as well as being unable to connect altogether.

We discovered part of our infrastructure wasn't provisioned appropriately, so it experienced performance issues and was unable to handle all the traffic. We intervened to make the needed capacity changes in order to resolve the trouble.

5:55 PM PST

We've identified the issue and deployed a fix. If you are still affected, please reload Slack with Command/Control + Shift + R as that should resolve the issue for you. Apologies for the disruption we caused, and thank you for your patience.

9:40 AM PST

Some people may being experiencing difficulties trying to log in to Slack. We’re investigating and will be back with an update shortly.
