Yellow / AC-2 (Atlantic Crossing 2) is a submarine telecommunications cable system linking the United States and the United Kingdom. The cable is wholly owned by CenturyLink (formerly Level 3 Communications) in the US following its acquisition of Global Crossing.^[1] The original owners, which each owned two of the fibre pairs, gave this cable system different names, so it is known as both Yellow (after the Beatles song Yellow Submarine) and AC-2. It has a capacity of 320 Gbit/s as of January 2007, upgradeable to 640 Gbit/s.
