Quantum/CenturyLink internet woes in West Seattle: Here’s what the company says

We’ve been hearing from West Seattleites who say their Quantum/CenturyLink internet service has been having intermittent trouble for the past week or so – particularly a “degradation of service” in the evenings. One of them, Dan, has been gathering reports via social media, summarized as follows:

The Problem:

Severe slowdowns occurring daily from approximately 5:00 PM to 11:30 PM
Latency spikes 10-30 times normal levels
Packet loss between 3-10%
Download speeds dropping below 1 Mbps
Web pages loading extremely slowly
Video streaming quality significantly reduced or failing entirely

Chloe, the first to send us that summary, added: “Despite multiple reports, residents are struggling to get meaningful responses from CenturyLink regarding resolution timelines.” Here’s how they’ve been advising others who are affected to escalate:

-Document the issue by running network diagnostics during outage periods
-Email CenturyLink executive escalation at: exec-escalation@lumen.com
-Use subject line: “West Seattle Evening Service Degradation – [Your ZIP Code]”
-Include specific details: times affected, technical data if available, impact on daily activities

After hearing about this from multiple readers over the weekend, today we asked parent company Lumen about the problem. Our query was answered by global issues director Mark Molzen:

We know how critical reliable internet service is to our customers and understand that service issues can disrupt daily routines like streaming, browsing, and staying connected.

We’re actively reaching out to customers to better understand the scope of the issue and work with them directly.

We’re committed to resolving this issue as quickly as possible and restoring the reliable service our customers expect. We appreciate their patience and engagement as we work through this.

So if you’re caught up in this, let us know if you get some relief.

    Thank you Chloe. I just escalated as she recommended. My wife and I work from home and this service disruption has made it incredibly hard to take Zoom calls. It’s been so bad that I’m seriously contemplating switching (back) to Comcast.

    • Jacob September 9, 2025 (7:08 am)

      I already am. CenturyLink’s terrible support had me actually jump ship and I have a Comcast install this morning. Switching from 1gbit/1gbit to 2gbit/0.2gbit, so some ups and downs on paper, but the real thing I’m relieved about is that Comcast at least has people that pick up the phone and a physical location you can go to. Ask me again how I’m feeling a couple months in LOL

      • Greg September 9, 2025 (5:52 pm)

        It’d take far worse than a few days of latency spikes to switch me to Comcast. 

      • DG September 10, 2025 (11:01 am)

        We switched to the 2gb service and I’ve never seen the number that high.  Our main computers are run hardwired with Cat 6 (and one Cat 7) cabling to unsure the faster I/O.  Wifi on the rest of the stuff in the house.  On the hardwired rigs, it maxes out at 960mbps with a 3ms ping.  I’ve reported it a number of times and just get tech gobbledygook responses. AND FYI.. do NOT expect anyone at Quantum to understand how to set up an APPLE system.  I knew more than my tech did.

  • Admiral Nerd September 8, 2025 (9:51 pm)

    Thanks for posting about this so we know we are not alone. We are in Admiral and have noticed the same pattern – even began saving data on ping speed (latency), download/upload speed, and packet loss (transmission errors) to compare “regular” service and those evening windows. We figured CenturyLink would try to sell us “upgraded service” rather than admit the problem is with their equipment or bandwidth. We will continue to do that and will try the recommendations here re reporting. Their own tools & metrics will almost certainly be able to show them that this problem is happening and that it is due to them – very disappointing that they won’t proactively address and take responsibility. We have not yet been “actively reached out to” for what it’s worth.

  • Roman September 8, 2025 (10:01 pm)

    We switched to T-Mobile 5G and haven’t looked back. Everything works as good as it did before, and we have a house of folks using it daily. It was cheaper for us monthly and they gave us a rebate to join. It was a no brainer. But I would check your coverage map to make sure you’re in range. 

    • j September 9, 2025 (6:14 pm)

      Same here. Its working great for me in Arbor heights. I switched after a couple of century link outages where they told me it would take a week to get a tech out. 

  • Anne September 8, 2025 (10:05 pm)

    Typical non answer by CL -good luck. 

  • ProbablyYourNeighbor September 8, 2025 (11:08 pm)

    Thanks WSB for adding visibility to this- we’ve been experiencing this for near enough two weeks, and both times I’ve contacted Century Link they’ve done “everything we can do short of sending someone out” and then directly said signing up for/switching to Quantum would resolve the issue.

    I would’ve been happy to do that, but they couldn’t get the internet I’ve already paid for working and Quantum appointments were ~3 weeks out (so about five weeks total w/out functional internet). Signed back up for Comcast/Xfinity, which I never would have imagined happening.

  • Missing piece September 9, 2025 (1:21 am)

    Our friends in Ballard are having this very same problem for a week. Not sure how wide spread this goes???

  • RS September 9, 2025 (2:12 am)

    I’m in south Admiral, SE of the high school and I haven’t had any noticeable issues in the last 2 weeks. Are you using their DNS or Google (or other) DNS?

    • Nathan September 9, 2025 (7:38 am)

      This is not DNS related. This is overall ping and throughput for everything. Rebooting ONT and testing directly with another router has the same issues. My experience is around 7-8pm start most nights and until at least 10pm, usually later. Ping goes from 2ms avg to 40ms and throughput goes from 900+Mbps to mostly under 10Mbps down and 50-300 up. Live TV streaming and online gaming is pretty much not possible. California Ave sw near Holden. 

      • George September 9, 2025 (10:00 am)

        Yes, this! I’ve experienced this almost every night. I’m near the STEM school on Delridge. Rebooting the ONT and the router does nothing. The problem happens to hardwired devices directly into the router as well, so not a WiFi issue.

  • Kt September 9, 2025 (5:37 am)

    We have Century Link, by Westwood Village, and are having no issues.  But they recently upgraded all the lines around here.  Very reliable for us.  Hope the affected users get some relief. If you have at mobile cell service, you can run your zoom calls by using your phone as a hot spot to connect your lap top.  I have done that successfully when away from home.

  • KellyS September 9, 2025 (5:57 am)

    I can say our Xfinity internet has been acting sketchy the last couple of weeks.  Intermittent drops while streaming our TV.

  • Drop them! September 9, 2025 (7:05 am)

    Try out 5G home internet from your mobile carrier.  We kept both for a while but recently cut the fiber off completely .  We stream TV, work on Zoom and have security cameras simultaneously on Verizon 5G with no issues.   It’s $40/mo.    You should test which carrier has the best coverage at your home but it’s cheaper and reliable.   Centurylink service is antiquated and difficult to navigate.   T mobile is advertising for $35/mo!

  • ChrisM September 9, 2025 (7:09 am)

    I asked for high-speed internet, they installed on the wrong unit of our condo complex and then started charging me, even though I had no service. Any attempt to escalate had service reps place me on hold for over 30mins and then they’d just hang up. After 6 months of this, they sent my bill to collections. They are an awful company to deal with, worst customer service of any of the data carriers, would never use them again as I dealt with so many levels of incompetence I’m surprised they’re still in business, Look at their reviews elsewhere, it is simply the same story all over. Even that canned awful generic PR response above was souless and shows they’re not actually solving the problem, they just want to present a response like they care…same fake messaging you hear during the hold time when you call for support. Overall, they’re terrible, would recommed Astound or Comcast, as they’re also not great, but better than the worst.

  • CW September 9, 2025 (7:10 am)

    South of Westwood village experiencing the same issue described by Chloe and others. Tech came out during the day and say “no, all good”. Called service again, never came but company emailed us that they completed the service. No help when calling in the evening or during slowdowns. The only time Quantum is helpful is when they are selling you something. Switching to a different service until they pull the same stunt and we’ll rinse & repeat.

  • Joe K. September 9, 2025 (7:58 am)

    Can confirm in Gatewood also. FWIW the problem started on 8/23 and has been a daily occurrence during the times listed above. Sunday 9/7 was perhaps the was the worst day so far with latencies and packet loss starting earlier around noon and peaking at the usual times 5PM-11PM. I did call/chat with CL last week and they scheduled a service visit for this Friday.  Lastly, yesterday (9/8) had minor disruptions starting at 4:30PM and ending around 6PM. By far the best day in over two weeks. So maybe the issue is fixed? Insert sarcastic emoji.

  • WS Local September 9, 2025 (8:46 am)

    Glad to hear I wasn’t the only one.  I was without internet for 2 days.  I called CL multiple times and spent hours on the phone with very little help and no viable solution.  They then said I need to upgrade to their latest technology, wait for a tech to come out and they then switched out my hardware.  It has been working well for the most part since then but they have been awful and infuriating to work with.                

  • 22blades September 9, 2025 (10:46 am)

    We’re leaving CenturyLink. If our economy is abandoning traditional dorms of transactions, these companies need to truly be treated as utilities at the national & local level. We broke up Ma Bell but we’re right back to those times; “We don’t care. We don’t have to.”

  • Dan September 9, 2025 (11:27 am)

    Hey all – we gathered a group of almost 80 people in a discord channel over the past few days from all over West Seattle who were impacted by this and last night was the first night in two weeks we saw no elevated latency or packet loss. A member of the group got confirmation yesterday “they found the issue with the congestion and was sending a technician out to resolve it yesterday evening” which lines up with this fix. Also trying to get more details on the exact problem, what the resolution was, and how they are going to prevent this from happening going forward.

    • BR September 9, 2025 (12:46 pm)

      Thanks Dan for the update…..that’s great news!  We have been dealing with this for the past couple of weeks and I must confess that I did not notice the lag last night.  I do have a technician coming out on Friday that I will probably cancel if I don’t see the problem the rest of the week.

    • Other Dan September 9, 2025 (4:46 pm)

      (I am not the same Dan).  Thanks Dan!  That matches up with what I saw on my router logs – I pay for both quantum/CL and Comcast, and have it automatically switch between the two based on connectivity/etc.  It was dropping quantum for Comcast every day for awhile.  Two weeks is a lot faster resolution than I experienced with Comcast (business) having a similar sporadic packet loss issue ten years ago (different neighborhood).  Still sucks :(

    • divine September 14, 2025 (11:33 am)

      Smokeping!  Love that tool. I’ve installed it for decades.

  • mem September 9, 2025 (11:48 am)

    Just lost mine in South Delridge.

  • JB September 9, 2025 (11:56 am)

    Ive been having slow service 7:00pm-11:00pm past 5 days or so. Called Quantum yesterday and explained problem and they did a “Refresh” on their end (not the same thing as a modem refresh).  Call took about 15 minutes.  All good last night after the call hope my problem is fixed cross fingers!

  • aa September 9, 2025 (12:31 pm)

    T-Mobile Home Internet all the way.

  • Mellow Kitty September 9, 2025 (12:36 pm)

    As a customer, I can say the only thing CenturyLink is committed to is raising prices and reducing the quality of service. My “locked in rate” has doubled over the last few years. We have two choices over here, garbage service or really garbage service. 

  • beaner66 September 9, 2025 (1:47 pm)

    If you have a Century Link account, you can log in and redeem a small adjustment to your bill for “an outage”. It was only a few dollars, but I just did it. I just happened to discover this while looking up something in my account a while back, now I check whenever there is a lag/lapse. After being logged in for a minute, the adjustment option pops up at the top of the screen. Maybe if enough people do it might send a message.

  • fluffy September 9, 2025 (5:02 pm)

    Wellp, I’d been thankfully immune to this issue in White Center, until tonight, when suddenly it’s affecting me as well.

  • Mike September 9, 2025 (5:53 pm)

    Everyone suggesting going for carrier 5G internet is ignoring the data cap that T-Mobile implements. 1.2TB of WiFi is easier to get to than you might think. 

  • Kj September 9, 2025 (7:23 pm)

    Quantum fiber/century link was great when they first came to ws, but not anymore! I went back to xfinity/ Comcast about 6 months ago and am actually very satisfied with the service. They match the monthly flat fee. Don’t wait for quantum to sort themselves out could be forever.

  • Mary September 10, 2025 (4:01 am)

    Just a heads up that Century link has notified many customers in our West Seattle  area in the past couple months to let them know they are getting rid of service in the area, and that at anytime it can be shut off.  In our area the City does not have adequate electrical set up to switch to non wi-fi service without thousands of dollars of our money to upgrade the power poles and lines.   Tried T-Bolbile but did not work great and now trying to figure out another option. Century Link’s service over the years was not great as well and like others getting any customer service help was challenging.  Thnanks to those who posted about bill reduction info.
    Also Quantum FIber is the one that told us and others that the City did not have the lines to offer us their service without the high personal costs.

  • valvashon September 10, 2025 (9:22 pm)

    North Admiral area- I have been testing and I regularly get 100 Mbps up and 100 Mbps (well, 97 tonight) down (via wi-fi) which is exactly what I am paying for.  Streaming, game playing (apparently) and regular internet use, no problems noted.  I have my own smart switch to do the VLAN tagging and my own router so the only CL thing in the house is the ONT (Optical Network Terminal).  Maybe I avoided the problem by not using their equipment.

Sorry, comment time is over.
