Maintenance every other week, nothing changes...?

michael · 2025-07-08T01:38:25+00:00

Been getting these maintenance messages every other week for what feels like almost a year now. Internet never goes out, and the “maintenance” is done almost instantly (the message goes away within 5 minutes). Still on low split. Nothing ever changes, same speeds, same channel SNR/Power/Frequencies. Should I be hopeful for FDX? or What’s going on here?

Stuff It seems like I might be on low split forever too. Not a single area in Tucson AZ has been upgraded to mid split that I know of. Tucson was also listed as an “Enhanced Speed Market” when they were initially doing the upgrades, but then it got removed for some reason. Comcast has literally zero competition in 99% of their areas in Tucson, so maybe they don’t feel the need to actually upgrade anything.

I was looking at the FCC National Broadband Map for your area. It seems to be a mixed bag, depending on what area of Tucson AZ you are in. COX has a much larger footprint in comparison to Xfinity. I couldn’t find any areas were Comcast offers more than 1200/35 Mbps. On the other hand COX has upgraded a lot of there area to 2000/100 Mbps, especially were there’s fiber competition. But it’s not unheard of for Comcast to upgrade a area straight from Sub-Split to DOCSIS 4.0, in areas with no competition. Some areas of Colorado, and California went straight from Sub-Split to DOCSIS 4.0. So It’s hard to predict what Comcast is going to do with there upgrades. I’ve compared the nodes from my city, Stockton that’s on Mid-Split, to nodes in another city Citrus Heights that’s on DOCSIS 4.0. I can’t tell the difference, they look identical on the outside to me.

Some Mid-split in City West of Me In Michigan.

Woodhaven Michigan has quite a bit along Van Horn road in terms of Mid-split, but it stops before gets past the Freeway, Nothing close to Trenton as yet according to FCC Broadband Map lol

And looks like entire Apartment building north of me in Riverview Michigan along busy road–according to FCC Broadband Map. though nothing on this side of the busy 4 lane road as yet

Meanwhile i’ll just keep waiting patiently

bigcoda …If you check there outage map, during the outage. It almost always list the cause as, Network Improvements…

I’ve noticed that they seem to have six different reasons for the outage when you click on the blue outage dot on the outage map:

Network Damage
Our network has sustained damage that makes us unable to deliver your services.

Unanticipated Network Repairs
Sometimes we discover a necessary repair during the day and work to fix it.

Network Impaired
Something is causing our network to not perform in the way we expect.

Network Improvement
We’re working hard to build the Next Generation Network to deliver even faster more powerful, and more reliable Internet. Services are impacted while we make these updates. Learn more about our network improvement efforts at xfinity.com/network.

Technician in your area
To make sure your XFINITY services are performing optimally, we’ll be doing some work in your area today. While we’re working, you could experience brief interruptions to your service. We apologize for any inconvenience caused by our work.

Legacy TV, X1 TV, Internet, Voice, Internet TV unavailable
We’ve detected a network performance issue in your area and we’re working to make improvements as quickly as we can; you may experience a temporary Xfinity service interruption during this time. We’ll have you back up and running by approximately XX/XX/XXXX XX:XX AM/PM (Arizona). We apologize for any inconvenience and appreciate your patience.

azdeltawye Forgot two, “Power Outage”. Channels, DVR, Legacy TV, Internet, Voice, Internet TV outage detected. You may be experiencing issues with your Xfinity services due to a power outage in or around your area. If you have power in your home, the network in your area may be damaged or without power. Once powered is restored and the area is safe, we’ll have you back up and running by approximately XX/XX/XXX XX:XX PM. Stay safe and we appreciate your understanding. Power supplying your home or the Xfinity network may be out.

Network Damage is the generic reason whenever a outage occurs. After a few minutes or up to 20 mins later, I will notice the outage cause will update to “Power Outage”. I think the XOC changes the outage reason in the system to power outage after investigating the issue. But all the modems dropping offline due to a power outage triggers a generic Xfinity outage for Network Damage to start with.

Thankfully, the Alpha XM3-HP in my neighborhood has working battery backup so my modem does not lose sync during a power outage.

“Severe Weather”- You may be experiencing issues with your Xfinity services due to severe weather in or around your area. Once the area is safe, our teams will begin to repair the network to restore services by approximately XX/XX/XXX XX:XX AM. Stay safe and we appreciate your understanding. Always fun to watch the outage map as a Hurricane approaches Florida lol, then boom all the outages for Severe Weather pop up.

There are several status updates:

Under Investigation
Technician on the way
Repair In Progress

These are not always updated though. For local node outages, these status updates often work great. For CRAN fiber cuts, sometimes things will sit on “Under Investigation” throughout the entire outage. or “Technician on the way”. Or things may say “Repair In Progress”, meanwhile Law enforcement/paramedics still have the scene contained and repairs have definitely not started yet. It is OK though, status map does not need to be 100% perfect, I use it to help me best assess the outage situation.

Stuff these messages are a dime a dozen. What you really want to see is a xfinity truck parked next to your node. Then you’ve got a possibility for mid-splits and docsis 4.0.

hex0101 Network Damage is the generic reason whenever a outage occurs.

Lol, I’m starting to think Network Improvement, we’re working hard to build the Next Generation Network. Is a generic reason for planned maintenance in your area. Lol, I highly doubt there doing Network Improvements, and working hard to build the Next Generation Network, almost every week? Otherwise I would have DOCSIS 4.0 or fiber symmetrical speeds available to me.

michael

Don’t know if it’s just a bug, or if it means anything… but the 400 / 600 / 1100 / 1200 / 1300 Plans are back showing on the broadband labels page after the most recent “planned maintenance”. I doubt they’re already reversing their whole simplified plans thing already, so I’m leaning towards it just being a bug.

hex0101

michael Showing the same thing at my address as well, and there hasn’t been any planned maintenance lately.

Mid-split addresses are showing the old 2100 tier now as well.

cypherstream

michael not here still 300/500/1000/2000. Doesn’t matter if you click 5 year price guarantee or 1 year plans.

Devious

I always just look at the rate card as that will tell you what speed tiers are supported for your area.

badtlc4

michael System doesnt show that in my area. Still only 300, 500, 1Gbps & 2Gbps for me.

Everything was displaying correctly for me, up until about two weeks ago. Now everything is a hot mess on there site. broadband labels page is blank for all post paid plans, prepaid is still showing. Plan builder page is broken, sometimes it won’t do anything after inputting address. When the plan builder page decides function, the broadband label is blank, missing for that plan. The chat box opens up on left side, is blank with no way to close it out.

@michael lol now there is maintenance

hex0101

@michael Maintenance canceled.

hex0101

Maintenance scheduled.

michael

hex0101 Nothing is scheduled over here in AZ. Hopefully your area is getting some actual upgrades done.

jweaver

That’s standard plant or node maintenance.

hex0101

jweaver Active for the entire town.. not just my node. Funnily, this time, the neighborhoods served by Harmonic CableOS nodes with mid-split amps show no maintenance pending. Sub-split nodes are showing maintenance.

Usually, both types have maintenance performed at the same time. Sometimes the time is off by an hour or day for each type. Seems to depend.

jweaver

hex0101 Standard plant maintenance then for work being done at the headend, since it affects all nodes likely connected through that same CMTS. Could be something as simple as a config change at CMTS, CMTS being selected to test update deployments (some broader updates for X1 and gateways show as maintenance sometimes), and/or an update for the CMTS itself.
