# Edgio

Edgio, Inc., formerly Limelight Networks, was an American company that provides a content delivery network (CDN) service, used for delivery of digital media content and software.
Following a 2022 acquisition of Edgecast, the company re-branded as Edgio, and now includes edge computing and cybersecurity services, such as DDoS mitigation.
As of January 2023, the company's network has more than 300 points-of-presence and delivers with 250+ terabits per second of egress capacity across the globe.
The company went bankrupt in 2024 and ceased operation on 15 January 2025.

## Company history

Edgio was founded in 2001 in Tempe, Arizona as Limelight Networks, a provider of content delivery network services. The company's Limelight Orchestrate Platform delivers Live and On-Demand video and online content to any connected device anywhere in the world.
In July 2006, the company closed a $130 million equity financing round led by Goldman Sachs Capital Partners. Limelight Networks later raised $240 million in an initial public offering, during June 2007, selling 16 million shares at $15. In April 2008, company founder Michael Gordon was recognized as a "Streaming Media All-Star" by StreamingMedia Magazine, for his contributions to the industry.
In January 2021, Limelight Networks and its board of directors announced that Bob Lyons has been named as the new president and CEO of Limelight Networks, Inc. and will join the company and the board of directors effective February 1, 2021. Mr. Lyons was formerly CEO of Alert Logic.
In September 2021, Limelight Networks acquired Moov Corporation, which did business as Layer0. The acquisition of Layer0 added website orchestration and workflow products, now part of Edgio's Applications suite.
On June 16, 2022, Limelight Networks completed the acquisition of Edgecast from Yahoo! Inc. and rebranded itself to Edgio. The acquisition of Edgecast expanded the reach of Edgio's global delivery network, and also added enterprise-class security solutions to the product portfolio. Additionally, Edgecast brought the Uplynk product - a video workflow and orchestration tool for the streaming of live and on-demand events. Following this acquisition, Edgio developed two distinct offerings - its Applications suite, consisting of website orchestration and cybersecurity solutions; and its Media suite, consisting of media delivery on its global edge network and video streaming solutions.
Edgio had received several industry accolades. In November 2022, an Industry Analyst firm, Quadrant Knowledge Solutions, conducted research into the commercial content delivery network services marketplace and named Edgio as a Leader in the 2022 SPARK Matrix Report.
In March 2023, another leading Industry analyst firm, IDC, categorized Edgio as a Major Cloud Platform for Cloud-Native PaaS Solutions.
In early June 2023, Frost & Sullivan assessed the holistic web protection platform industry and based on its findings, recognized Edgio with the 2023 Global Customer Value Leadership Award.
In late June 2023, GigaOm, a technology focused analyst firm and media company, awarded Edgio the Leadership and Outperformer position in its latest GigaOm Radar for Edge Platforms v3 Report. Edgio was recognized as the leader in the graphic and several tables, and defined as a platform player with maturity within the market.
In July 2023, Edgio was recognized as a Leader in the Frost Radar: Global Content Delivery Network, 2023, by research and consulting firm Frost & Sullivan.
On 9 September 2024, Edgio filed for Chapter 11 bankruptcy protection. The company plans to sell its assets to Lynrock Lake LP, a private equity firm, for around $110 million. Akamai Technologies purchased Edgio's customer contracts and patents among assets.

## Technologies

Edgio operates its own private network with more than 250+ terabits per second of global egress capacity. The network consists of dense clusters of specially configured servers in more than 300 delivery locations (points-of-presence) which are interconnected through the company's global network and connected to more than 1000 Internet service provider (ISP) networks. Edgio caches web content for its customers in multiple delivery locations around the world, serving it to users from the fastest location. A private fiber network backbone between its delivery locations allows cache-fill traffic and dynamic content to bypass the public internet and improve the delivery speed of content. This architecture is managed by intelligent proprietary software that increases the speed of delivery with fewer cache misses and can scale to handle surges in end-user demand. Edgio networks mainly uses FreeBSD as operating system on their infrastructures.

### The Edgio Platform

The Edgio Platform is composed of services including content delivery, video packaging and content management, web acceleration, cloud security (including DDoS and WAF protection), and cloud storage.

## Patent lawsuits

In June 2006, Limelight Networks was sued by Akamai Technologies and the Massachusetts Institute of Technology over alleged patent infringement. In April 2009, the District Court for the District of Massachusetts ruled that Limelight Networks did not infringe, overturning the February 2008 finding of a Boston jury. Similarly, in December 2007, Limelight Networks was sued by Level 3 Communications over alleged intellectual property and patent infringement. In January 2009, a jury ruled that Limelight Networks did not infringe. Akamai Technologies appealed part of the decision. On April 20, 2011, the United States Court of Appeals for the Federal Circuit granted the petition by Akamai Technologies for rehearing en banc its appeal in Akamai Technologies, Inc. v. Limelight Networks, Inc. The order vacated the earlier opinion of December 20, 2010. The order includes a request to file new briefs addressing this question: If separate entities each perform separate steps of a method claim, under what circumstances would that claim be directly infringed and to what extent would each of the parties be liable?
On August 31, 2012, the Court of Appeals for the Federal Circuit issued its opinion in the case. The Court of Appeals stated that the trial court determined that Limelight did not directly infringe on Akamai's patent. A slim majority in this three-way divided opinion also announced a revised legal theory of induced infringement, remanded the case to the trial court giving Akamai an opportunity for a new trial to attempt to prove induced infringement. On December 28, 2012, Limelight filed a petition asking the Supreme Court to review the decision of the Federal Circuit regarding the standard for induced infringement in cases where multiple parties may perform various steps of a patented claim. Akamai filed a cross petition asking the Court to also review the standard for direct infringement in those cases. On June 24, 2013, the Supreme Court asked the Solicitor General to weigh in on the petition for certiorari. In June 2014, the Supreme Court reached a unanimous decision rejecting Akamai's claim of "induced infringement".
On July 1, 2016, it was announced that the Massachusetts District Court entered the final judgment in the case, with Limelight paying $51M in total damages to Akamai (to be reflected in Limelight's 2016 Q2 earnings).
