Cable giant Comcast said Wednesday service had been restored to thousands of customers who a day earlier suffered widespread phone outages from coast to coast.

In a statement, the Philadelphia-based company said: “We’re happy to report the situation is resolved. We’re very sorry for the disruption this outage may have caused to our business customers.

“All systems are up and running, but some customers may need to reboot their equipment. We’re here to help, so please contact us at (800) 391-3000 if you have any further issues.”

The outages started around 2 p.m. Tuesday and were most numerous in Atlanta, Chicago, Houston and Seattle, according to reports. Businesses used social media to persuade customers to contact Comcast by email to find out what was going on.

Comcast said the outages affected voice services for small- to medium-size businesses, but not Business VoiceEdge or PRI Trunking lines.
