Incident history
LAST 90 DAYSAbout AT&T outages
Written by the HostTracker monitoring team · updated from live probe data.
AT&T spans mobile service, home internet and fibre, and a large enterprise backbone, so "is AT&T down" covers several very different failures. A mobile outage stops calls and data on the handset; a home-internet outage takes out an entire household including anything that depends on it; and a backbone problem can disrupt traffic for businesses that never think of themselves as AT&T customers. Because the company operates critical infrastructure, its incidents attract immediate attention and sometimes regulatory scrutiny, and they are frequently regional, tracking the specific facilities involved. If your own connection is the one that failed, you cannot rely on it to tell you what is happening - an independent check from outside your network is the only reading you can trust in that moment.
Common causes of AT&T downtime
Configuration or software changes applied to core network equipment, the root cause behind several of the largest nationwide mobile outages
Regional fibre cuts and power events that take out home internet and mobile backhaul across a defined geographic area
Device-registration and provisioning failures that leave phones showing signal while calls and data will not connect
Account portal and billing-site outages that are entirely separate from network service - the website can be down while your connection works perfectly

Questions people ask during an outage
The live probe run on this page tests att.com from a broad sample of HostTracker's 300+-location monitoring network - many independent networks at the same moment, rather than just your own connection. If every location fails to reach it, the outage is real and affects everyone; if only a few locations fail while most load normally, the problem is local to those regions or networks rather than AT&T being fully down. A single refresh from your own browser can never make that distinction, because it only ever tests from one vantage point on one network.
Yes. HostTracker lets you add any URL - including third-party services you depend on, not just your own website - as a monitored target, and notifies you automatically the moment it becomes unreachable. Before sending an alert, HostTracker re-verifies a failure from multiple locations in its 300+-location network, so you're notified about real, confirmed outages rather than a single location's momentary blip. The free plan checks two monitors every 30 minutes indefinitely at no cost; paid plans check as often as once a minute, with alerts available through SMS, email, voice call, and several messenger apps.
No - as of the most recent check, att.com is responding normally to HostTracker's monitoring network, and has been up for 2d 19h. Over the last 24 hours it recorded 100.00% uptime across 0 incidents. If it is failing for you specifically, the cause is local - your network, DNS cache, or a regional route - and the live probe results above will show which locations, if any, are affected.
Carrier incidents are regional far more often than nationwide, so the useful question is how wide the failure reaches. The live check on this page tests att.com from monitoring locations spread across many networks and countries at once: if nearly every location fails, you are looking at something central; if most succeed and only probes near you fail, the problem is regional, and it is on AT&T's side rather than something to fix on your equipment. Note that the website and the mobile network are separate systems - att.com can respond perfectly while cellular service in your city is disrupted, so treat a healthy website as evidence about the website only.
Start at the equipment: if the gateway shows no upstream sync at all, the fault is between you and the provider - the line, the ONT, or the local infrastructure - rather than something inside your home network. If the gateway is online but nothing loads, the problem sits further upstream in routing or DNS. Either way you will need a second connection to investigate: use mobile data to run the multi-location check here, which tells you whether AT&T's own services are reachable from the outside world. Widespread failures point to a provider incident; a healthy result everywhere else means the issue is specific to your line and worth reporting.
