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.
OnApp CDN is a federated content delivery network designed for hosting providers, utilizing spare capacity in OnApp Clouds to deliver content globally. It supports HTTP push, pull, and streaming/live streaming, catering to hosting providers and enterprises managing web content delivery. The platform integrates with OnApp Cloud, enabling users to leverage a network of edge servers for improved performance. It is primarily used by service providers and enterprises needing scalable CDN solutions. The service is operational as of August 16, 2025, with recent updates enhancing its reporting capabilities.

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.
OnApp CDN operates a global network of Points of Presence (PoPs) by leveraging spare capacity from OnApp Clouds, though specific PoP counts are not publicly detailed. It uses a federated model, combining edge servers from multiple cloud hosts to ensure broad geographic coverage. The platform supports content delivery across regions including North America, EMEA, APAC, and others, with synchronization between CDN and OnApp Cloud occurring every 20 minutes by default. Regional strengths include flexibility for hosting providers, but limitations may arise from reliance on third-party cloud capacity, potentially affecting consistency in less dense regions.
