As part of our filing for Chapter 11 bankruptcy relief, Akamai has acquired select assets from Edgio, including certain customer contracts from our content delivery, applications, and security businesses, but not including Uplynk. We encourage any active Edgio delivery, applications, or security customers that are not already engaged with Akamai to migrate their services, to contact their local Akamai office or support@edg.io as soon as possible to help avoid service interruptions. Service will end on January 15, 2025.


Any Edgio Uplynk customers can reach out to support@uplynk.com for any questions or concerns.
