Overview
Rackspace Technology, founded in 1998, offers a content delivery network (CDN) designed to accelerate content delivery by caching assets closer to users. The service integrates with Rackspace’s broader cloud offerings, including Cloud Files, and supports businesses needing reliable content distribution. It is primarily used by enterprises leveraging Rackspace’s managed cloud services, particularly those with complex infrastructure needs. The CDN is built to reduce server load and improve user experience through global content distribution.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.
Network & Architecture
Rackspace CDN operates a global network with points of presence (POPs) across North America, EMEA, APAC, and Latin America, though specific POP counts are not publicly detailed. It leverages partnerships with major cloud providers and uses Akamai’s infrastructure for content delivery. The service is optimized for integration with Rackspace’s cloud storage but may have limited flexibility for standalone CDN use. Its global footprint ensures low-latency delivery for enterprise customers, with a focus on North America and EMEA.

It supports programmatic control over caching, domains, and content refreshes. Real-time logs are available for monitoring, but there’s no public support for Terraform, SDKs, or CI/CD integrations. Migration tools are limited, primarily designed for integration with Rackspace’s Cloud Files.
