LITTLE ROCK — AT&T says a "vast majority" of the thousands of customers who lost television, Internet and phone service Monday have had their service restored and the rest should be back up Thursday morning.
The telecommunications giant said in a statement that it would provide a credit for customers who lost service.
"We know our customers count on their U-verse service and we apologize for the inconvenience," the statement said.
AT&T said Wednesday that the problem was spurred by a "complex issue related to a software upgrade."
U-verse went down Monday night for many customers across multiple Southern states including Arkansas. Officials say the problem affected less than 1 percent of AT&T's 7.4 million U-verse customers, which would mean fewer than 74,000 customers.
The company said a multiple-day disruption is "unusual."
Some customers in the Little Rock area reported on Twitter that service was restored Wednesday night, while others said it remained out.
