Overview
Limelight Networks, later rebranded as Edgio, was a content delivery network (CDN) provider founded in 2001, specializing in digital media and software delivery. It offered services for video streaming, web acceleration, and content delivery with a global network. The company ceased operations on January 15, 2025, following a Chapter 11 bankruptcy filing in September 2024, driven by mismanagement, failed acquisitions, and operational challenges.
NS1, now IBM NS1 Connect, specializes in DNS traffic steering and MultiCDN solutions to optimize application delivery. Founded in 2013 and acquired by IBM in 2023, it serves enterprises needing precise control over traffic routing across multiple CDNs and cloud providers. Its flagship product, NS1 Connect, uses real-time data and automation to enhance performance and resilience. Customers include large-scale organizations in tech, finance, and media sectors. The platform integrates with various CDNs and cloud services to manage global traffic efficiently.
Network & Architecture
—
NS1 operates a global network with 26 points of presence (PoPs) across North America, EMEA, APAC, and other regions, ensuring low-latency DNS resolution. Its architecture leverages authoritative DNS and real-time data for traffic steering, with robust peering to major cloud providers and CDNs. The platform supports hybrid deployments, combining on-premise and cloud DNS for flexibility. It excels in global coverage but may have less focus on niche regional markets like Africa or the Middle East compared to telecom CDNs.

History & Notes
Limelight was a key player in the CDN market, delivering content for major events like the 2008 Olympics and Obama’s inauguration. Its 2022 acquisition of Edgecast aimed to expand its edge computing and security offerings but led to integration challenges and talent loss. Financial restatements in 2023 and a slowdown in internet traffic growth further strained operations. Some assets, like the Uplynk platform, were acquired by Lynrock Lake LP, while Parler Cloud Technologies purchased Edgecast’s CDN business. No official EOL notice remains publicly available.
