Is Armstrong down? How to check for an outage and what to do

Armstrong posts outages in your account rather than on a public map. Here is how to confirm one, what to try while you wait, and who to call.

Covers Armstrong residential internet, TV and phone. Business customers have separate support lines, listed below.

How to check if Armstrong is down

1. Check My Account. Sign in at armstrongonewire.com. A notice across the top of the dashboard means Armstrong knows about an outage in your area.
2. Turn on outage alerts. In My Account you can sign up for text or email alerts so you hear about outages and fixes without calling.
3. Check Armstrong's social media. During the October 2026 outage, Armstrong posted updates and restoration notices there.
4. Look at outage trackers. A sudden spike on Downdetector or similar sites from your area points to a wider problem.
5. Test on a wired device. If a computer plugged into the modem has no connection, the problem is Armstrong's service, not your Wi-Fi. Our speed test shows whether you're offline or just slow.

The October 21-22, 2026 Armstrong outage

Armstrong customers lost internet, TV and home phone service on the evening of Wednesday, Oct. 21. Outage reports spiked between about 6 and 8 p.m. ET, with problems reported in western Pennsylvania, the Mahoning and Shenango valleys in Ohio, and other Armstrong areas. Armstrong's app and website were hard to reach for some customers, and phone wait times ran long.

Armstrong blamed an issue in its network and said most service was restored by the next morning, though some customers in Butler County were still without service on Oct. 22. Butler County Emergency Services reminded residents to use cell phones for 911, since cell service wasn't affected.

Armstrong phone numbers

All numbers from armstrongonewire.com, Oct 2026. The main support line also handles technical problems around the clock. During big outages, chat and the outage notice in My Account are usually faster than calling.

What the problem usually is

Fixes to try if there is no outage

1. Unplug the modem and router for a full minute, plug the modem in first, and wait five minutes before plugging in the router.
2. Check the coaxial cable at the wall and the modem; hand-tighten loose connectors.
3. If you use Armstrong's Wi-Fi pods (Plume HomePass), check that each pod has power and isn't too far from the main router.
4. Plug a computer into the modem with an Ethernet cable. If that works, the problem is Wi-Fi; see how to tell your internet from the service.
5. Still down? Call 1-877-277-5711 or chat, ask Armstrong to test your line, and get a ticket number.

Home phone during an outage

Armstrong home phone service runs over the same connection as your internet, so it stops working in an internet outage, and in a power outage unless you have battery backup for the modem. Keep a charged cell phone for 911. A small battery backup (UPS) for the modem and router can keep you online through short power cuts; see how to keep internet during a power outage.

Getting a credit

Armstrong doesn't publish an automatic outage credit. After service comes back, call or chat, give the dates and times you were out and your ticket number, and ask for a prorated credit. Outages that last a day or more are the easiest to get credited.

If Armstrong outages keep happening

Note the dates and times of each outage; a pattern helps when you ask Armstrong for a technician visit or a credit. To compare, see what else serves your address with our address check. In much of Armstrong's area, 5G home internet from T-Mobile or Verizon, or Starlink in rural areas, can work as a main connection or a backup; see backup internet options.
