Slack imports are not importing messages into channels successfully

Technical summary:
On November 29th at 9:03am PT, we made a change that restructured how we filter channels IDs during imports. This had a negative effect on the import tool, and we failed to retrieve public channel messages from the export file during Slack to Slack imports.

After identifying the problem, our team deployed a fix at 10:40pm PT. Going forward, all new imports are now working as expected. If, however, you do experience any issues, please let us know at

8:50 PM PST

We've been given the all-clear! The import tool is working as expected once more. Apologies for interrupting your day.

10:48 PM PST

We have located the cause of these import tool issues and are working on a fix. Please hold tight.

10:31 PM PST

We are looking into reports of messages not being imported correctly into channels from the import tool. Apologies for this hassle. We are working to get this sorted as quickly as possible.
