About this network

Fastly's Autonomous System. Fastly is a modern edge-cloud / CDN known for very fast cache purges and programmable edge logic (VCL, Compute@Edge).

What it's used for

• Caching and accelerating high-traffic sites and APIs, with near-instant content invalidation.
• Edge compute and edge security for developer-heavy customers.

Notable

• Fastly deliberately runs fewer, larger points of presence than some CDNs, favoring powerful POPs at major interconnection hubs.
• Many well-known sites front through Fastly, so an IP here identifies the CDN, not the origin.

Interesting

• A single misconfiguration at Fastly in June 2021 briefly took a large chunk of the web offline — including major news, government, and retail sites — illustrating how concentrated CDN infrastructure has become.
