Reports first seemed to surface on Twitter last night from Comcast customers tweeting that their Internet service had gone down. Comcast's own customer service Twitter feed, known as Comcastcares, confirmed the outage, initially pointing to an issue in Boston but soon revealing that the problem was more widespread.
Comcast spokesman Charlie Douglas told CNET through e-mail that last night Comcast engineers identified a server issue that affected Internet service for customers primarily in the Boston and D.C./Beltway areas.
Though the outage focused on Boston and Washington, D.C., a Comcast customer service technician reportedly told NBC News that there were "significant Internet outages" in Connecticut, Maryland, Virginia, Massachusetts, New York, and New Hampshire, according to MSNBC.com.
