Searches for "Comcast e-mail" and "Comcast error code 400" dominated Google's top searches Saturday morning as customers were unable to sign in. Through the outage, Comcast's Director of Digital Care Frank Eliason repeatedly responded to customers who tweeted that their e-mail was down with information on the outage and the estimated time that service would return -- 1 p.m. Eastern on Saturday.
BusinessWeek reports that it was Eliason who initially suggested that Comcast use Twitter to interact with its customers. Eliason said he realized he could find service complaints to address by searching for "Comcast" on Twitter. Other companies have followed his lead on using the site to update customers, and BusinessWeek called Eliason "the most famous customer service manager in the U.S., possibly in the world" because of his Twitter initiative.
Comcast is the second-largest Internet service provider in the country. So when its e-mail service goes down, there are a lot of frustrated people who can't sign in to check their mail. The company is using the social blogging site Twitter to keep customers updated and assure them that Comcast cares with the Twitter feed @Comcastcares, according to a report on AppScout.com.
