Texas-based cloud computing company Rackspace was founded in 1998 and is quite the household name. With their ‘Fanatical Support’ concept, the company distinguishes itself from its competitors by offering to focus on service and support rather than technology.
The core businesses of Rackspace are dedicated servers and cloud servers, though the company has a large portfolio with web services. Among others, the company offers website hosting, application migration, Software-as-a-Service (SaaS) and Apps hosting, database and data analytics, email hosting and CDN services.
The company’s CDN is powered by Akamai, and Rackspace resells a custom map with 200 points-of-presence (PoPs):
Note that a limitation to the Rackspace CDN is that clients can only add up to 10 domains (resources) per service.
Rackspace offers a free web-based application called Rackspace Marketplace that enables clients to manage a variety of business applications in a single place. Some of the partnered apps in the Marketplace can also be purchased directly via Rackspace. Currently, the Rackspace Marketplace has integrations with:
Other * New Relic * Cedexis * Neustar UltraDNS * Dynatrace * W3 Total Cache
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.
