Overview
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.
Warpcache was a Netherlands-based MultiCDN provider founded in 2015 by Wouter Spee and Thijs de Zoete. It specialized in combining multiple CDN platforms into a single service, using Cedexis data for real-time routing and optimization. Warpcache offered granular steering down to the ASN (Autonomous System Number) level, giving customers more precise control than country-level MultiCDN services of the time.
The company was acquired by System73 in 2019. Following the acquisition, Warpcache’s independent MultiCDN platform was discontinued, and its domain later redirected to SimpleCDN. Today, SimpleCDN operates as a single CDN service rather than a MultiCDN integrator.

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.
Warpcache was notable for being one of the first turnkey MultiCDN platforms alongside TurboBytes. Its focus on ASN-level performance routing set it apart from competitors who worked at broader country-level granularity. Although the brand and platform no longer exist, Warpcache helped shape the early MultiCDN ecosystem.
