Cloudflare’s Always Online and the Internet Archive Team Up to Fight Origin Errors

This post details the integration of the Internet Archive's Wayback Machine with Cloudflare's Always Online service. This partnership allows Always Online to serve archived copies of webpages when a customer's origin server is down, enhancing website availability and contributing to the Internet Archive's mission. The integration involves sharing hostname and popular URL information with the Internet Archive for crawling and archiving, and when an origin error occurs (520-527 status codes), Cloudflare first checks its local cache and then fetches the most recent archived version from the Internet Archive to serve to visitors, displaying a banner to indicate the origin is unreachable.
