When the internet goes down at a Boulder home, check with your provider first. No public government list shows the outage. Xfinity and Quantum Fiber each show outages for your address in their app and on an outage map, and both send text alerts once you have set them up. T-Mobile sends a network outage notice when maintenance or a problem affects the tower you use most. If you work or study from home, set up two things before the next outage: a way to check your provider's status from your phone, and a second connection to use while the first one is down.

The federal government does collect outage data, but it does not publish it outage by outage. The FCC set outage reporting rules in 2004. Under them, wireline, cable, satellite, wireless, interconnected VoIP and Signaling System 7 providers must report outages that last at least 30 minutes and meet other thresholds. Those filings are presumed confidential. The FCC also runs the Disaster Information Reporting System (DIRS), which collects daily infrastructure status once the FCC activates it for an area. Each activation is announced in a public notice that lists the counties or municipalities covered. Individual DIRS filings are presumed confidential too, but during an activation the FCC publishes daily public communications status reports with aggregated service status information. Your backup options also depend on where you live: some parts of Boulder have more internet choices than others.

What Remote Workers and Students Need from Home Internet

When the connection drops in the middle of a video call or an online class, you need four things from your provider.

A status check that works without home WiFi. If a modem or SmartNID can't reach the internet, the WiFi it feeds stops working as well. Any outage tool you depend on has to work over your phone's cellular data or by text. A provider website you can only reach through the broken connection won't help.

Alerts that come to your phone. Both wired providers text outage updates, but only after you set them up. Xfinity texts numbers registered for Xfinity texts, and only for certain outages. Quantum Fiber texts you about an outage at your address only if service notifications are turned on. T-Mobile lets customers know once a network outage is resolved, and that notification usually comes within two days.

A clear way to get a credit. Xfinity and Quantum Fiber handle credits differently. Xfinity applies a credit automatically once you submit its eligibility check, if your account qualifies and hasn't reached the maximum credit limit. Quantum Fiber asks you to call and request one.

A backup connection. At Quantum Fiber, the most common causes of outages include storms, power outages and network equipment problems. Of those, a power cut is the one you can prepare for at home, with a battery backup unit (BBU). Storms and equipment failures on the provider's network need a second connection that doesn't depend on that network.

Top Picks for Remote Workers and Students in Boulder

These picks compare how each provider handles an outage. They do not rank price or speed. For how the wired networks have held up over time, see Boulder internet reliability: Comcast vs CenturyLink.

Xfinity

Cable and fiber home internet from Comcast.

Visit Xfinity →
  • Xfinity: app, map and text checks. Sign in to the Xfinity app, and if your location is affected, it shows the outage type and cause, the estimated time to fix, and the status of repairs where available. The outage map searches any address Xfinity serves, so you can check from a phone on cellular data. If you have problems and no outage is listed, use the "Report an outage" link. To get outage texts, register your mobile number for Xfinity texts before the next outage. Registered numbers get texts for certain outages, with an estimated time to fix, periodic updates and a final message when service is fixed. You can also text OUT to 266278 (COMCST) to check for outages in your area; data and messaging rates may apply.

Quantum Fiber

Fiber-to-the-home internet with symmetrical upload and download.

Visit Quantum Fiber →
  • Quantum Fiber: map, app and text alerts once notifications are on. The outage checker takes your address and shows whether you're in an outage, and the app shows an outage banner at the top of the home screen. For text alerts, turn on Service calls and texts under Communication preferences in the app, or the "Phone" option for Account services under Notification Preferences on the web, before the next outage. With that setting on, an outage detected at your address triggers a text alert. If your number doesn't accept texts, you get a recorded voice message instead. The alerts come in order: a first notice with an estimated restoration time if one is available, updates as they come in, and a notice that service is back.

T-Mobile Home Internet

5G home internet over T-Mobile's wireless network.

  • T-Mobile 5G Home Internet: notices tied to the tower. A T-Mobile outage notice means one of two things: routine maintenance on the tower you use most, or an unforeseen problem affecting that tower. If the outage is severe, T-Mobile 5G Home Internet may not work until it's fixed. If your phone is also on T-Mobile, plan a backup that doesn't depend on that tower.

Setup Tips for Remote Workers and Students

  • Find your second provider on the FCC map. The FCC broadband map, currently a snapshot of the December 2025 data, shows which providers report service at your address. It shows availability, not outages. Our guide to checking a Boulder address on the FCC map walks through the lookup and how to challenge a wrong listing.
  • Plan the hotspot before you need it. If your phone isn't affected by the outage, turn on its hotspot from the spot in your home with the best signal. This works best when your phone and home internet don't share a network. A cable or fiber line at home with a phone on a cellular network gives you two separate paths.
  • Use Wi-Fi Calling when the cell tower is the problem. If your home WiFi is still up but cellular service is out, turn on Wi-Fi Calling for calls and texts.
  • Lighten the load on a degraded T-Mobile connection. If T-Mobile 5G Home Internet is slowed rather than down, cut back on downloads and streaming, disconnect unused devices, move closer to the router, and connect your device to the router with an Ethernet cable if you can.
  • Add a battery backup unit. Without a BBU, a power outage interrupts your Quantum Fiber connection until the utility restores power.
  • Restart the modem after the outage. Once service is restored, restart your modem or SmartNID before rejoining a call.
  • Check for a credit. For Xfinity, go to the Support page, scroll to "Outage map and credit," click "Check credit eligibility," and enter details about your outage. If you qualify, the credit is added to your account automatically. For Quantum Fiber, call 833-250-6306, 7 days a week, 7 a.m. to 11 p.m. CST, and ask for one.
  • Escalate to the FCC if the provider doesn't fix it. File an informal complaint only after you've tried to resolve the problem with your provider. Filing is free, and you don't have to appear in person. File at fcc.gov/complaints or by phone at 1-888-CALL-FCC (1-888-225-5322). Complaints the FCC receives include access and billing concerns and issues with advertised service speeds. The FCC may send certain complaints to the provider. If it serves your complaint on the provider, the provider must respond in writing, to you and the FCC, within 30 days of receiving it.
  • Report a dead spot to the state. The Colorado Broadband Office survey and speed test takes reports of locations without internet and speed test results. The data is anonymized and aggregated for public use. The office isn't conducting data collection right now, and it doesn't require ISPs to confirm their FCC availability filings with it.

Bottom Line

You won't find a public FCC list of Boulder outages. Outage filings go to the FCC. Since September 30, 2022, state agencies have had read-only access to NORS and DIRS filings, on the condition that they keep them confidential. The FCC also investigates major network outages, but individual reports stay out of public view.

For a Boulder household, the plan that works is your provider's own outage tool on your phone, with alerts turned on before you need them, plus a backup connection that doesn't rely on the same network. Don't wait for a new citywide fiber option. ALLO Communications ended its agreement to build a citywide fiber network in July 2026. The city issued a new Request for Information in September 2026, and the timeline for new internet service options is unavailable.
