Update

Cloudflare has identified an issue with our Pages feature: Customers under our Free plan using custom hostnames may experience specific pages unexpectedly returning zstd compression mode. Customers experiencing this issue can add a compression rule to enforce brotli or gzip compression to temporarily circumvent the problem. Nevertheless, we are working to mitigate this issue, more updates to follow shortly.
