Summary
Lumen (CenturyLink / Level 3, legacy Time Warner Telecom)
backbone transit datacenter
A legacy Autonomous System now under Lumen Technologies (via CenturyLink and Level 3), historically the TWTC Time Warner Telecom network. Primarily a large US enterprise backbone and transit network that also underpins Lumen's colocation and edge services.
What it's used for
- Enterprise connectivity, IP transit, and hosting/colocation for business customers on Lumen's network.
Notable
- More of a carrier/backbone AS than a pure hosting host; addresses here are often business circuits rather than VPS.
- Part of a sprawling Lumen/CenturyLink/Level 3 AS family assembled through decades of telecom mergers (Level 3, Qwest, TWTC, and others).
Interesting
- Time Warner Telecom (TWTC) was a US competitive carrier absorbed into tw telecom, then Level 3, then CenturyLink, and finally rebranded as Lumen.
