AT&T DSL Outage — Is AT&T DSL Down?
Track AT&T DSL internet outages in real time. DSL customers share local DSLAM equipment — a single equipment failure can affect an entire neighborhood.
AT&T DSL delivers internet over copper telephone lines. While AT&T is actively upgrading DSL customers to fiber in most markets, millions of homes still rely on DSL service. DSL outages often affect multiple customers simultaneously since they share DSLAM (Digital Subscriber Line Access Multiplexer) equipment at local AT&T facilities.
AT&T DSL Not Working? Step-by-Step Fix
Follow these steps before calling AT&T
1
Check your DSL modem lights
Look at the DSL light on your AT&T modem: solid green = connected, flashing = attempting to connect, red or no light = no DSL signal from the line. A red DSL light means the issue is on the line, not your equipment.
2
Check your phone line
Pick up a landline phone and listen for a dial tone. No dial tone usually means a line issue AT&T needs to repair. If you have dial tone but no DSL try restarting your modem.
3
Restart your DSL modem
Unplug your modem from power, wait 30 seconds, plug back in. Wait 2 minutes for the DSL light to go solid green.
4
Check your phone connections
DSL travels over your phone line — ensure the phone cord from the wall jack to your modem is secure. Try a different wall jack if available.
5
Consider upgrading to fiber
If you are on DSL you may be eligible for AT&T Fiber at att.com/internet. Fiber is faster, more reliable, and replaces your DSL service at no additional install cost in most areas.

Frequently Asked Questions
Why is AT&T DSL so unreliable?+
DSL uses copper telephone wiring that was designed for voice calls, not high-speed data. Copper degrades over distance, is susceptible to moisture and corrosion, and ages over time. Customers far from the DSLAM often see worse speeds and more frequent outages than those nearby.
Is AT&T discontinuing DSL service?+
AT&T has been phasing out DSL in markets where fiber is available. If fiber is available at your address AT&T may have already or will soon discontinue your DSL service. Check at att.com/internet for fiber availability at your address.
Why does my DSL go out when it rains?+
Rain and moisture are common DSL outage triggers because water gets into aging copper line connections and reduces signal quality. Persistent rain-related outages usually require an AT&T technician to inspect outdoor wiring and connections.
How is DSL different from fiber outages?+
DSL outages are often localized to one customer or a small group sharing a DSLAM port. Fiber outages typically affect a larger area since a single fiber node serves many more customers but the infrastructure is more reliable overall.
