Incident

File uploads are failing for some workspaces

Issue Summary:

Due to an upstream provider removing an IP address from service, some customers were unable to upload files and connect to Slack. We requested customers flush their DNS cache in order to purge the IP address. Please reach out to feedback@slack.com if you’re having any trouble uploading files or connecting to Slack.

Folks have reported that flushing DNS cache has resolved the file upload issue some of you have experienced; however, please let us know at feedback@slack.com if that’s not the case.

We're continuing to look into file uploads failing, but haven't solidified a root cause yet. We'll keep you updated as we move forward in our investigation.
