What we track for Lumen / CenturyLink right now.
Counted from Lumen / CenturyLink’s own public network disclosures. Timelines vary by service and location, and a filing can be amended or withdrawn.
What this does, and does not, mean.
Carrier transition activity detected in or relevant to this market.
This does not by itself establish that your specific line will be disconnected. A Critical Line Assessment can verify the service and dependency.
Network-change and copper-retirement filings are not the same thing as a service-discontinuance event. What a filing does establish is that the window to identify your dependencies is closing.
Lumen's filings usually describe the affected facilities in enough detail to summarize, so we publish our own plain-English summary beside the facts and link the official document. Some filings name a footprint rather than a single state; those are counted but cannot be placed on the state table below.

Lumen / CenturyLink notices by state.
A state appears here because at least one Lumen / CenturyLink filing names it. The date column is the soonest effective date still ahead of us in that state, taken from the filing itself.
A further 170 Lumen / CenturyLink filings name a footprint or facility rather than a single state, so they are counted in the totals above but cannot be placed on this table.
Most recent Lumen / CenturyLink filings.
Each entry links to the original document on the carrier’s own disclosure site. Where our source terms allow a link but not a restatement, we publish the facts and the link, and nothing else.
