AT&T: Some progress made in restoring some of its network

(CNN) – AT&T says it has made progress restoring some of its network after thousands of customers reported cell service outages.

More than 64,000 customers reported issues with placing calls, texting or accessing the internet, according to tracking site Downdetector.

Some Verizon and T-Mobile customers have also reported disruption, but both companies say their networks are not experiencing an outage.

It’s likely their customers have had issues trying to connect to those on the AT&T network.

An industry source says there’s no indication the outage was caused by a cyberattack or other malicious activity.

They say it appears to be related to how cellular services handoff calls from one network to the next.
