About this network

Merit Network is a non-profit research and education network serving Michigan — and one of the most historically important organizations on the internet.

What it's used for

• Backbone and internet connectivity for Michigan's universities, schools, libraries, and government (R&E, not consumer).

Notable

• Merit operated the routing and engineering of the NSFNET backbone in the late 1980s and early 1990s — the network that grew into the modern internet — in partnership with IBM and MCI.
• Still a live, member-governed non-profit today, not a relic.

Interesting

• Founded in 1966, Merit predates the internet itself; its name comes from "Michigan Educational Research Information Triad."
