Issues with connectivity and file uploads

Technical Summary:
On October 1st between 8:11pm PT and 8:22pm PT, Slack experienced issues that prevented some users from connecting to their workspace. The ability to view or upload files was also affected.

A configuration change at 8:11pm PT caused any new app connections to fail. For connected users, the ability to view and upload files was also affected. This change was reverted at 8:22pm PT.

We are currently hard at work on scoping preventive measures to ensure this doesn’t happen in the future.

12:52 PM PST

Everyone should be able to upload their files and access Slack once more. We're truly sorry for disrupting your day.

8:22 PM PST

We are looking into reports of people having trouble accessing their workspaces and uploading files. Apologies for this disruption.
