Issue summary:
From 10:12 AM PST until 10:25 AM PST on December 14, 2022, some customers had trouble loading Slack workspaces, sending messages, and uploading files.

Prior to this issue, we began removing traffic from an isolated location within a data center region as part of a planned exercise. Upon further investigation, we identified a bug within this process. We then stopped the process, which resolved the issue for all users. Error rates were monitored for a short while prior to announcing the resolution, in order to ensure the issue was fully resolved and would not reoccur.

2:00 PM PST

This issue is resolved, and all users should be able to load Slack, send messages, and upload files once again. We appreciate you bearing with us in the meantime, and we apologize for the disruption to your day.

Some users may be experiencing trouble loading Slack workspaces, sending messages, and uploading files. We're investigating the situation and we'll let you know once we have more information to share.
