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.
