The mitigation is being deployed, and the search cluster has completed it's maintenance. We're monitoring the stability of the service until those complete.

We've identified a change in our search client library that introduced retry behavior that is causing the search issues to cascade. A fix has been identified and is being deployed that should bring PyPI's main interface back up until the search cluster completes it's maintenance.

The search cluster restart inadvertently caused all the incoming search requests to timeout, overloading our backend processes and causing a wider outage. Uploads, the Simple Index, Package file hosting, and JSON APIs are still operational, but pypi.org's main UI is currently unavailable until the search cluster recovers.

The search cluster node that failed was automatically removed from the cluster and search is operational. We're working to restore the failed node and bring the cluster fully back online.
