Overview
Internap Holding LLC, formerly Internap Corporation (INAP), was a provider of data center, cloud, and content delivery network (CDN) services, founded in 1996 and headquartered in Norcross, Georgia. Its CDN, once a key offering, leveraged the VitalStream platform and Managed Internet Route Optimizer (MIRO) for optimized content delivery. The company served enterprises, including IPTV providers like NetMax Media, with a focus on performance through its Private Network Access Points (P-NAP). In 2023, Internap rebranded to HorizonIQ, shifting focus to bare metal cloud and colocation services. Its CDN operations have been discontinued, and the company now operates as a cloud-focused business.
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.

History & Notes
Internap’s CDN, built on VitalStream and MIRO, was a notable player in the 2000s, with expansions in London, Tokyo, and Hong Kong. Financial challenges, including a $99.7M goodwill writedown in 2008 and multiple bankruptcies, led to asset sales and a pivot away from CDN services. The 2022 ransomware attack on ServerIntellect further disrupted its hosting operations, prompting the final shift to HorizonIQ. No official EOL notice for the CDN is publicly available, but the rebranding and asset sales indicate a complete exit from the CDN market.
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.
