June 2026: Bitbucket authentication failures affecting sign-in and Bitbucket-backed accounts
Pulumi Cloud experienced authentication failures for users signing in with Bitbucket identities, causing failed sign-ins and intermittent errors in the Console and API after session tokens expired every two hours. The issue was caused by an incident with Atlassian's Bitbucket OAuth service, not Pulumi's infrastructure, and affected Bitbucket-connected accounts and integrations while users with GitHub, GitLab, email, or SSO identities remained unaffected. The incident was resolved after approximately 11 hours when Atlassian deployed a fix for their OAuth service.
