Flow patterns (42-month cumulative)
Inbound (numbers acquired)
| Direct transfer from another RespOrg | 12,717.0 |
| Harvested from disconnect pool | 72.0 |
| First assigned from spare pool | 2,061.0 |
| Reactivated own disconnects | 0.0 |
Outbound (numbers lost)
| Direct transfer to another RespOrg | 69,375.0 |
| Standard disconnect aging process (3+ months in DISC) | 4 |
| Abbreviated disconnect period (1–2 months in DISC) | 31 |
| Released directly to spare pool | 1,821.0 |
Of the 35 disconnect episodes this RespOrg has sent through aging, 89% were abbreviated (1–2 snapshots in DISC status). That's a strong early-disconnector signal — this RespOrg routinely releases numbers before the full 3–4 month aging window. Worth checking daily for vanity drops.

Summary
CenturyLink is part of Lumen Technologies offering quantum fiber, a fully digital platform for delivering fiber-based products and services to residences and small businesses. They have changed names and grown through acquisitions, and use resellers. That means if your number is with them, it may have been serviced by a different organization. It also means that they may have numbers stuck in the cracks.
