Overview
Limelight Networks was founded in 2001 and historically headquartered in Tempe, Arizona. It delivered web assets, software downloads and live/on-demand video over a private global CDN.
The company added Layer0 application tools in 2021, then acquired Edgecast and changed its name to Edgio in June 2022. Limelight is retained as a historical brand rather than a separate current subscription.
Network
Limelight used a private backbone and distributed delivery infrastructure connected to access networks.
Edgio later distinguished the Limelight-derived EdgePrism network from the acquired Edgecast/Sailfish network. For an existing account, confirm the current delivery network and its coverage before choosing a replacement.
Past features
Historical services
- Content caching, web delivery and large-file downloads.
- Live and on-demand video delivery.
- Layer0 application delivery and developer tooling.
- Separately offered DDoS and web application firewall services.
These describe the pre-rebrand portfolio. For an existing account, ask the current provider which services are supported and test the replacement API configuration.
Service status
Limelight became Edgio in June 2022. Akamai bought selected Edgio delivery and security customer contracts in December 2024, along with non-exclusive patent rights. The purchase excluded Edgio personnel, technology and network assets.
For a former Limelight or Edgio account, confirm the current provider and migration status, then test the features your application needs.
