I wouldn't expect them to be integrated for at least another decade. Global Crossing AS3549 still exists with over 2,000 peer ASNs, yet Level 3 acquired them in 2011. Time Warner Telecom was acquired in 2014 and it still has 89 peer ASNs.

Centurylink bought Digital Teleport in 2003 and their ASN is still out there.

Subject: CenturyLink/Level 3 combined AS

Hey all,

Are there plans for CL and Level3 to combine AS's into one network? 

If not, do they actively peer and route traffic through each other's networks at least?

Basically we're looking at picking up 1G of CL and wondering if it's near the same quality as Level3 in terms of latency and packet loss.

Thanks
