Identified

Cloudflare has identified an issue with our API which potentially impacts multiple customers: Performing bulk requests to our Custom Hostnames API endpoint might return unexpected timeouts, although only observed on a small percentage of requests.
This does not affect the serving of cached files via the Cloudflare CDN or other security features at the Cloudflare Edge.
