Overview
BT (British Telecom), founded in 1846, is a major UK telecommunications provider offering CDN services through its edge infrastructure. It leverages the Streaming Video Alliance’s Open Caching technology, developed with Cisco and Qwilt, to deliver content for 8K video and AR/VR applications. The service targets enterprise customers, particularly those needing high-capacity video delivery. BT operates under its EE brand for mobile services and Openreach for broadband infrastructure. Its CDN is designed to handle modern streaming demands, serving media companies and large-scale businesses.
Cedexis was a MultiCDN platform specializing in real-time traffic steering and performance monitoring, optimizing web and cloud application delivery across multiple CDNs and data centers. Founded in 2009 by Julien Coulon and Marty Kagan, it was acquired by Citrix in 2018 and integrated into its Intelligent Traffic Management (ITM) product. The platform was used by enterprises, including media outlets like L’Equipe, Le Figaro, and Le Monde, to enhance global web performance. Cedexis is now defunct, with its ITM product reaching end-of-life (EOL) in October 2025.
Network & Architecture
BT’s CDN uses a global network with points of presence (PoPs) integrated into its extensive telecom infrastructure, though specific PoP counts are not publicly disclosed. It employs Open Caching to turn existing telecom infrastructure into a federated CDN, optimized for low-latency delivery of high-bandwidth content like 8K video. The network benefits from BT’s EE mobile coverage, reaching over 99% of the UK population, and Openreach’s fibre backbone. It has strong regional presence in EMEA, particularly the UK, with peering optimized for European traffic. Coverage in APAC, LATAM, or other regions is less emphasized.

Pricing
BT’s CDN pricing is enterprise-focused, typically requiring custom contracts rather than pay-as-you-go or public per-GB rates. No free tier or public pricing details are available. Interested parties must contact BT’s sales team for quotes, as pricing is tailored to large-scale deployments.

Integrations & DevEx
BT provides an API-first interface for managing CDN configurations and accessing real-time logs. Documentation is available at https://www.bt.com/about/developers. There is no public mention of Terraform support, SDKs, or specific CI/CD integrations. The focus is on enterprise integrations for media delivery, with limited emphasis on developer-centric tools or migration utilities.
—
When it fits
- Enterprises needing high-capacity video delivery, especially for 8K or AR/VR content, leveraging BT’s telecom infrastructure.
- UK-based businesses requiring strong regional performance with EE and Openreach integration.
- Organizations seeking custom enterprise CDN solutions with direct support from a legacy telecom provider.
—
When it doesn’t
- Small to medium businesses looking for pay-as-you-go or transparent pricing models.
- Developers needing extensive edge compute, serverless functions, or advanced security features like WAF or DDoS protection.
- Companies prioritizing global coverage outside EMEA, as BT’s network focus is heavily UK and Europe-centric.

History & Notes
—
Cedexis was known for its Radar, Fusion, Sonar, and OpenMix tools, which provided real-time visibility and programmable traffic management across CDNs and clouds. Its acquisition by Citrix aimed to bolster hybrid and multi-cloud performance but faced challenges, including a notable DDoS attack in May 2017 impacting French media clients. The decision to sunset ITM reflects Citrix’s strategic shift, with no reported plans for a direct successor. NS1 Connect has emerged as a key alternative, leveraging similar DNS-based steering technology.
