Bitbucket authentication failures affecting sign-in and Bitbucket-backed accounts

Update timeline

1. investigating Jun 11, 2026, 10:20 PM UTC

   We are investigating an issue affecting customers who sign in to Pulumi Cloud with a Bitbucket identity or use Bitbucket-connected accounts. Beginning at approximately 06:00 UTC on June 11, requests to refresh Bitbucket authentication tokens began failing. Affected users may experience failed sign-ins with Bitbucket, as well as intermittent errors in the Pulumi Console and API after their current Bitbucket session token expires (these tokens expire every two hours). Integrations that rely on Bitbucket credentials may also be affected. Our investigation indicates the failures originate from Bitbucket's OAuth token service rather than Pulumi infrastructure, and we have engaged Atlassian support. Customers using GitHub, GitLab, email, or SSO identities are unaffected. Workaround: Customers whose Pulumi account has an additional sign-in method (GitHub, GitLab, email/password, or SSO) can continue to sign in using that method. We will post updates as the investigation progresses.

2. identified Jun 11, 2026, 10:56 PM UTC

   Atlassian has acknowledged an incident affecting Bitbucket OAuth login, which is the cause of the Bitbucket sign-in and authentication failures affecting Pulumi Cloud. Their incident is being tracked at: https://bitbucket.status.atlassian.com/incidents/h51sr145gsmx The issue is external to Pulumi, and no action is required from Pulumi customers. Until Atlassian resolves their incident, customers signing in with a Bitbucket identity may continue to experience failed sign-ins and intermittent Console and API errors after their current session token expires. Customers using GitHub, GitLab, email, or SSO identities remain unaffected. Workaround: Customers whose Pulumi account has an additional sign-in method (GitHub, GitLab, email/password, or SSO) can continue to sign in using that method.

3. monitoring Jun 12, 2026, 12:02 AM UTC

   Atlassian has deployed a fix for their incident affecting Bitbucket OAuth login, and we have confirmed that Bitbucket authentication requests from Pulumi Cloud are succeeding again. Error rates have returned to normal levels and sign-in with Bitbucket is working.

4. resolved Jun 12, 2026, 12:17 AM UTC

   The incident has now been resolved and the service is operating normally for all customers.
