This incident has been resolved. Login via Slack is operating normally again, and no further action is required.

### identified, 2026-10-02 22:33 UTC

Some customers on Slack Enterprise Grid who sign in with Slack are seeing Slack-originating errors when logging in. We've raised this with Slack and are monitoring for a fix. Customers using SAML sign-in aren't affected. Alert ingestion and our On-call product's paging functionality are unaffected.
