Company

Company Tata Communications Lumen
Short profile Tata Communications is a full service, carrier grade, global CDN that has been in operation since their acquisition of BitGravity in 2012. The CDN rides on Tata’s global infrastructure which is the largest Tier 1 network in the world. Tata’s ownership of the network and peering relationships enable it to be very competitive when it comes to price. Lumen (formerly known as Centurylink or Level 3) owns and operates a global Tier-1 network and - logically - their CDN runs on top of it. Lumen CDN has POPs on many continents and their product focus is on video, large object delivery and edge computing.
