    Some users may experience authentication failures or errors when using extension action packs (e.g., Jira, Confluence, Outlook, Teams). Users attempting to authorize or use these extensions may see HTTP 401 or 500 errors. Our engineering team is actively deploying fixes to affected environments. We expect recovery to progress incrementally as the mitigation completes across deployments. We will continue to closely monitor system behavior as the mitigation completes.

  1. identified May 08, 2026, 06:20 AM UTC

    The incident was triggered by an AWS availability issue affecting underlying compute and storage in a single availability zone. That event left the search cluster without a healthy master node, which caused search requests to time out or fail. During recovery, the master node could not restart because its persistent volume was still marked in use on the impacted instance, delaying failover until the volume attachment problem was resolved and healthy search capacity was restored. This is affecting only the AWS hosted instances. Please refer AWS status page: https://health.aws.amazon.com/health/status?path=open-issues

  2. resolved May 11, 2026, 05:07 AM UTC

    We have successfully restored all Glean instances in the us-east-1 region that were impacted by the recent AWS EC2 outage.

    The issue of authentication errors for Jira and Confluence is now resolved. The root cause was an IP block from Atlassian which was triggered by a spike in the number of user token requests. We have worked with Atlassian to get the IP block removed. We have also made fixes to fail gracefully when Atlassian starts returning errors for auth requests.
