CenturyLink Down? CenturyLink Network Status in Real Time
Status computed from public network signals (BGP and active probes) on CenturyLink's infrastructure, updated every ~10 minutes. This is not an official CenturyLink channel.
Is CenturyLink down right now? A red indicator below means a likely outage on the CenturyLink or Quantum Fiber network in your area; green while your own line is dead points instead to your modem, the fiber ONT or the copper into your home. To confirm in under a minute: check the live meter below, compare it with user reports on Downdetector, and run a speed test from your phone on cellular data with Wi-Fi off.

The chart shows the network signal level (BGP reachability and active probes) relative to the median of the last 24 hours: full bars = normal, low bars = possible outage.
What to do if CenturyLink is down
CenturyLink, now part of Lumen, sells two very different products under one name, and telling them apart is half the battle. Read the badge above first: if it shows a network outage, the fix is on Lumen's side and waiting is the realistic option. If it is green, check your own equipment.
On Quantum Fiber, the line arrives at a fiber ONT and feeds a C4000 or C5500 modem. Look at the modem's Internet or Broadband light: solid green means the fiber is up and the issue is your Wi-Fi or a device; red or off means the ONT is not seeing light, usually a cut or a dropped registration upstream. Power the ONT and modem off for 30 seconds, and if it will not come back green the fault is Lumen's.
On DSL, the connection climbs a copper pair back to a remote terminal or the central office, and the state of that pair caps both your speed and how dependable the link is. If the DSL light flickers on and on without ever holding, the line is failing to train — usually damp or worn copper that a technician has to attend to, not a fault a reboot will shift.
If the wired line is down, tether to your phone to stay online while the repair happens.
Why CenturyLink goes down: the usual causes
Each half of the network breaks in its own way. On Quantum Fiber, an interruption is nearly always mechanical — a digger through a duct, a joint that has failed, or an ONT that dropped its link after the power flickered — and the damage is contained to a street or a housing tract. DSL is the more temperamental of the two: it rides copper that many neighborhoods have had for decades, so a wet cross-connect, oxidation on the pairs, or a tired line card at the cabinet can silence a block, while very long loops stay marginal even in dry weather. When something bigger goes wrong across Lumen it is normally a routing change or a maintenance slip rather than one severed cable, and it recovers the moment the change is undone. A handful of the brief small-hours dropouts are simply scheduled work.
Is it CenturyLink or your own setup?
Let a measurement decide it. Put your phone on cellular, switch Wi-Fi off and run a speed test, then repeat it from a computer plugged into the modem with an Ethernet lead. A healthy cellular result beside a wired test that will not even establish a link tells you the trouble is on your line or in CenturyLink's plant; if the entire block has gone quiet, it is an area event. With DSL, a word with a neighbor on the same exchange is worth a lot, because one poor copper route often drags several homes down together.
Do not read slow as down. A stretched DSL loop that connects but hands you a sliver of a fiber plan is behaving exactly as copper does, so set your expectations by the technology on your wall. Units trip people up as well: a 940 Mbps Quantum Fiber plan tops out near 118 MB/s in a download window, which makes a reading in the hundreds of MB/s a success rather than a shortfall.
How to reach CenturyLink and confirm the status
The support line is 1-800-244-1111, and the CenturyLink app — or the separate Quantum Fiber app — will show an outage flagged against your address and let you raise a repair ticket. When you want a second opinion on whether the problem is shared, weigh the crowd-sourced complaints on Downdetector against the live indicator above. In a real event a quick look at social posts for your city usually settles the question within a few minutes.
Frequently asked questions
How do I know if CenturyLink is down right now?
The indicator at the top of the page gives you the quickest answer. It tracks public routing signals across CenturyLink's network on a roughly ten-minute cycle: red suggests a real outage, whereas green with your home still offline usually means the modem, the fibre ONT or the copper pair. Pair it with a Downdetector check and a cellular test before you queue on the phone.
Is it Quantum Fiber or my old DSL that's down?
The two products fail so differently that it pays to know which you have. Quantum Fiber terminates on an optical unit and stumbles mainly over cuts or a lost light signal, coming back once the line is mended. DSL leans on copper and reacts to damp, distance and age. Your headline speed and the box screwed to your wall usually give it away, and that in turn tells you how patient to be.
My modem's Internet light is red — what does it mean?
A red or unlit Internet light says the modem has no usable signal from outside — on Quantum Fiber the ONT is seeing no light, on DSL the copper will not lock. Kill the power to the ONT and modem for half a minute and let them find each other again. If the light refuses to turn green, the break is on CenturyLink's side and wants a ticket, not another restart.
Why is my CenturyLink DSL so much slower than fiber plans?
Copper loses speed with every foot of distance, so a long run to the cabinet simply cannot match fiber. On a DSL line, tens of Mbps up to the low hundreds may be all the pair can sustain — that is the ceiling, not a fault. The cure, where CenturyLink offers it, is Quantum Fiber, which sidesteps the copper altogether.
CenturyLink is slow rather than down — what should I do?
Split the test in two: wired and over Wi-Fi. Strong wired numbers pin the slowdown on your Wi-Fi, so move the modem, pick a cleaner channel or add a mesh point. If the wired figure alone stays far under your plan across several runs, log it and open a case. And mind the arithmetic — 940 Mbps is roughly 118 MB/s, so a download in the hundreds of MB/s is right on target.
How long do CenturyLink outages last, and can I get a credit?
A dug-up fiber or a copper repair that needs a van can stretch across several hours or into the next day, while a routing hiccup often clears inside one to four. If you lose service for far longer than that, jot down the start time and any ticket reference and ask CenturyLink to credit the outage on your next bill.
