What is "digex"

DIGEX was an early provider of Internet services in the United States credited with creating the "managed hosting" business. Its corporate predecessor, Digital Express Group, and then DIGEX provided dialup "Public Access Unix" shell accounts in the Baltimore-Washington region beginning in the fall of 1991. Digital Express Group, and thus DIGEX, was started by Doug Humphrey and Mike Doughney, in the basement of Mr. Humphrey's town house in Greenbelt, Maryland, in a fairly classic "Internet Startup" mode, offering dial-up access to the early Internet environment. DIGEX was a very early, if not the earliest, provider of "hosting" services, which would grow to dominate the company operations.
