AT&T network health

AS7018 AS20057 AS2386 AS6389 +6 moreNormal

SquidGrid measures 6,180 internet paths that cross AT&T’s network, from vantage points in 38 countries, and compares each path with its own normal latency. Snapshot 2026-10-04 17:34 UTC.

Right now

306 of these paths have a reading from the last six hours. The typical path is running +0.0 ms against its own normal.

Change vs each path’s normal	Paths	Share
Under +25 ms (normal)	305	99.7%
+25 to +50 ms (elevated)	1	0.3%
+51 to +150 ms (high)	0	0.0%
+151 ms and up (severe)	0	0.0%
Unreachable (no route)	0

Routing: 2 of AT&T’s measured paths sit inside a prefix that was withdrawn from BGP or changed route in the last two hours.

The last 30 days

Each bar is one UTC day: the share of AT&T paths we sampled that spent at least one hour 25 ms or more over their normal. A typical day is 3.7% (dashed line); a bar turns orange at twice that.

Is it AT&T, or the route to it?

A network-wide figure tells you whether AT&T as a whole is having a bad hour. It cannot tell you whether your traffic is affected, or where on the route it changes.

How to read this: a path’s normal is its own trended median latency, not a speed-of-light estimate. The bands follow SquidGrid’s state scale (+25 / +50 / +150 ms). The header reads Normal while under 2% of currently read paths are 25 ms or more over normal, Elevated from 2%, and Degraded from 10%. ASNs counted: AS7018, AS20057, AS2386, AS6389, AS7132, AS7287, AS14654, AS2686, AS2687, AS2688. Updated hourly; times in UTC. SquidGrid is not affiliated with AT&T.
