Telerama, the Shadyside-based internet service provider, has gone dark.

Email service from the company that helped to usher Pittsburgh into the cyber age when it was founded in 1991 as one of the world's first ISPs has been down since Wednesday, and DSL service since Wednesday, according to customers. Its website is down, and five of its six telephone numbers are now answered by recordings that say they are either disconnected or out of service. The sixth rings, with no answer.

In an April 4 email to a customer, Telerama founder Doug Luce wrote, "We're actually in negotations now to move service over to another local ISP. If that works out, we will actually be going out of business." However, the company has made no public announcements. A Post-Gazette email to Mr. Luce was not answered.
