This incident has been resolved.

As of 19:38 UTC on August 18, 2025, this incident has been mitigated. We'll continue monitoring but no longer expect any customer impact.

We are continuing to investigate. The potential impact also includes customer who have configured OAUTH and have changed their public key in any way, including refreshing it or creating a new public key during this incident.
We will post an update in 60 minutes, or sooner if mitigation has been achieved.

Starting at 08:00 UTC on August 18, 2025, some customers who have created or updated role based access control policies during this incident may see a delay in those new rules getting applied. Additionally, customers who have configured OAUTH where their public key is set to be refreshed during this incident may see additional authentication failures. This can impact clusters in any cluster regardless of region or cloud provider. We are currently investigating the issue. We will post an update in 30 minutes.
