Starting as early as at least 2022-10-26, users may experience a significant performance degradation when enabling HTTP/3 on their sites. Users are advised to disable HTTP/3 for better performance.
Update: Improvements have been made to HTTP/3 performance recently that greatly reduce the impact of this regression.
We have mitigated impact for all new deployments created with Pages CI/CD.
Users that are on wrangler version 3.60.0 should update to wrangler version 3.60.1 and re-deploy their Pages project in order to resolve 500 errors.
