Level3 Communications is an Internet Service Provider (ISP) and a provider of telecommunication services. The company was founded in 1885 and is currently headquartered in Colorado, in the United States. The Level3 brand is well-known; the company operates a large, physical network of the Internet and offers a wide range of networking services. Level3 is the network, and it owns a Tier 1 backbone and operates its own points-of-presence (PoPs). One notable customer of Level3 is Netflix.
Level3 has made some notable acquisitions, including companies such as Black Lotus (DDoS protection), TW Telecom (business Internet solutions), Genuity (AS1) and the CDN services business of Savvis - a subsidiary of CenturyLink that provides hosting and colocation services. The CDN was acquired in 2006 and is run by Level3 to this day. In 2016 Level3 has been acquired by CenturyLink.
Additional CDN-related services by Level3 include DDoS protection, SSL, Encryption, Geo Blocking, (live) video streaming and website acceleration.
Together with Fastly, CloudFlare, Highwinds, Akamai and EdgeCast, Level3 is part of the Google Cloud Platform CDN Interconnect program. The interconnection agreement between the backbones of both parties will benefit customers on both sides; traffic over these interconnects enjoys reduced latency and increased reliability compared to the public Internet. Clients using a Google Cloud origin receive a discount to their egress traffic when peering with Level3 or any other CDN that is part of the collaboration.
Level3 does not publish customer information. CDN overview has located some of customers of the CDN service, such as CloudVPS. We’ll keep the list updated.
CacheFly is a Chicago-based CDN provider, with over 40 Points of Presence (PoPs) spread over six continents. Next to the usual locations, Cachefly has PoPs in India, Qatar, Egypt and South Africa.

Instead of DNS-based global loadbalancing, the company’s CDN infrastructure relies on TCP Anycast routing.
