Summary
Cogent Communications
transit tier-1 backbone
Cogent is a large, low-cost Tier 1 IP transit provider with an extensive
international backbone, popular with data centers and hosting providers.
What it's used for
- Wholesale IP transit and dedicated internet access, often priced aggressively per megabit.
- Backbone connectivity into thousands of carrier-neutral data centers where Cogent has a presence.
Notable
- Cogent has a long history of peering disputes (notably with other Tier 1s and large content networks), which have periodically caused partial reachability problems between Cogent-only and rival-only customers.
- A very low AS number (174) reflects its roots in early internet registration.
Interesting
- Cogent grew largely by acquiring the assets of failed dot-com-era carriers, assembling a global network at bargain prices.
