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.
Peer5 operated a peer-to-peer (P2P) content delivery network (CDN) specializing in live video streaming, leveraging WebRTC for in-browser, clientless enterprise CDN (eCDN) solutions. Founded in 2012, the company was acquired by Microsoft in August 2021 to enhance video streaming capabilities in Microsoft Teams. Peer5’s technology optimized bandwidth usage through self-balancing mesh networks, serving large-scale enterprise events with up to 2 million concurrent users. As of 2025, Peer5’s standalone services are defunct, with its technology integrated into Microsoft’s eCDN for Teams.

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

Peer5 was known for its innovative use of WebRTC to create a decentralized, browser-based P2P CDN, reducing server load and improving video delivery for large audiences. The company powered events for over 1 billion users before its acquisition. No official EOL announcement for standalone services was found, but Peer5’s website now redirects to Microsoft’s eCDN page, indicating full integration. Some third-party sources mention continued support for existing Peer5 customers post-acquisition, but this is unconfirmed as of 2025.
