Fastly

Fastly, Inc. runs Autonomous System 54113, an edge-cloud platform with a programmable content-delivery network used by many of the world's largest websites and media companies. The network is known for near-instant cache purging, live and on-demand streaming delivery, and edge computing that allows customers to run logic close to their users. Registered in the United States, AS54113 fronts a range of high-traffic sites, and disruptions to it have occasionally caused visible outages across dependent services. It is a routinely observed origin for cached web content. Since Fastly fronts many unrelated customer sites, one address block can serve very different services depending on the incoming request.
