Timeline

  1. Sep 23, 2026, 5:38 PM UTC

    This incident is resolved. Between approximately 11:50 and 17:11 UTC, a portion of sign-in and sign-up attempts on openrouter.ai were incorrectly blocked with the message "This action was detected as suspicious and has been blocked." The cause was an infrastructure issue at our authentication provider that made one of its bot-protection checks fail, which in turn triggered a blocking rule. The provider disabled the rule at 17:11 UTC and sign-ins have succeeded normally since then. Existing sessions and API keys were not affected at any point, and there was no security breach or exposure of account data. If you were unable to sign in earlier, please try again. We apologize for the disruption.

    The provider has disabled the affected rule and new sign-ins, we are monitoring the recovery.
