Xfinity, operated by Comcast, is the largest cable internet provider in the United States serving over 32 million customers. When Xfinity internet goes down — whether from a neighborhood outage, cable damage, or modem issue — it affects remote workers, students, and households across entire ZIP codes. Understanding whether the problem is on Xfinity's end or yours is the first step to getting back online.
How to Check if Xfinity is Down in Your Area
1. Use the Xfinity My Account App
The Xfinity My Account app (available on iOS and Android) is the fastest way to check for area outages. Open the app on mobile data, navigate to the service status section, and Xfinity will tell you if there is a reported outage at your service address. The app also shows estimated restoration times.
2. Text "OUT" to 266278
Text OUT to 266278 (COMCST) from your mobile phone. Xfinity will reply with your current outage status and any estimated fix times. This works even when your home internet is down.
3. Visit the Xfinity Status Center
On mobile data, go to xfinity.com/support/status and log in with your Xfinity credentials. The status center shows real-time service health for your address and lets you schedule a technician visit if needed.

DownDetector shows a real-time map of Xfinity outage reports by city. A spike in your region confirms a neighborhood or city-wide issue rather than an isolated problem at your address.
5. Test Your Modem Directly
Connect a device directly to your Xfinity modem/gateway with an ethernet cable (bypassing your router). If you still have no internet, the problem is either with the modem itself or Xfinity's network. If ethernet works but WiFi doesn't, your router is the issue.
Protect your connection when Xfinity restores service
ISPs including Xfinity can throttle streaming and gaming. A VPN bypasses throttling and encrypts your traffic on shared cable networks.

Xfinity Troubleshooting: Step-by-Step
Step 1: Restart Your Equipment
- Unplug your Xfinity modem/gateway from power for 30 seconds.
- If you have a separate router, unplug that too.
- Plug the modem back in first; wait 2 minutes for full boot.
- Then plug in the router; wait another minute.
Step 2: Check for Area Outages
- Use the Xfinity My Account app on mobile data.
- Check if neighbors also have no service.
- Look for damage to cable lines in your area (after storms).
Step 3: If Modem Shows Red Light
- Confirm coaxial cable connection is tight at both ends.
- Check for Xfinity signal levels via the modem admin page (10.0.0.1).
- If signal levels are poor, call Xfinity to send a technician.

Xfinity customers can request a bill credit for extended outages. Here's how:
- Log in to your account at xfinity.com.
- Go to Account → Billing → Service Credits.
- Select the billing period and describe the outage.
- Submit the request — credits typically apply to the next billing cycle.
Xfinity does not automatically issue credits — you need to request them. For outages lasting more than 4 hours, you are generally eligible for a prorated credit.
Frequently Asked Questions
Why does Xfinity internet keep going out?
Recurring Xfinity outages are often caused by: aging coaxial cable infrastructure, signal degradation (check modem signal levels), congested node in your area, or a failing modem that needs replacement. Call Xfinity to run a remote diagnostic.
Is Xfinity down vs my router broken?
Connect your device directly to the modem with an ethernet cable. If you get internet via ethernet but not WiFi, your router is the issue. If no internet on ethernet either, it's Xfinity or the modem itself.
How do I report an Xfinity outage?
Text OUT to 266278, use the Xfinity My Account app, or call 1-800-XFINITY. Reporting helps Xfinity prioritize repairs in your area.
