Cogent Communications Holdings, Inc.

One of the world's largest Tier 1 internet service providers, Cogent Communications carries high-speed internet traffic, selling data transport and colocation to businesses and other carriers across North America, Europe, and Asia. Founded in 1999 by Dave Schaeffer in Washington, D.C., it grew during the early-2000s telecom downturn by snapping up the fiber networks of more than a dozen struggling rivals at bargain prices. The name "Cogent" means "clear, logical, and convincing."
