Comcast phone outages hit businesses nationwide

Comcast customers nationwide reported phone service outages Tuesday afternoon.

Businesses from Florida to Washington took to social media to ask customers to get in contact by email as Comcast landlines went down.

According to Outage.Report, a website that tracks service outages, a majority of the problems were reported in the Chicago, Houston, Seattle and Atlanta areas.

The outages appear to have started before 2 p.m. ET, when a community manager posted about reports of the service disruption in a forum for Comcast Business. The company confirmed the issue is ongoing around 4:40 p.m.

"National engineering is actively working to resolve this issue," wrote the manager, who goes by the handle Comcast_John.

The outage affects voice services for small- to medium-size businesses, according to Comcast, and does not affect the company's Business VoiceEdge or PRI Trunking lines.
