[ About Cogent Communications ]

Cogent Communications — public profile.

Cogent Communications operates AS174, a global Tier-1 IP backbone with one of the largest European metro footprints by city count. Cogent is known for an aggressive commercial model and an extensive on-net building list.

[ Why Cogent Communications + DFDC ]

How Cogent Communications integrates with THG1.

Cogent is present in the THG1 meet-me area, available as a direct cross-connect or via the BareFABRIC IP transit blend. Useful where shorter AS_PATH into smaller European NSPs matters.

    How a deployment with Cogent Communications looks in practice.

    In the Internet Port blend

    AS174 sits in the Internet Port upstream mix. Traffic egresses over Cogent Communications where BGP selects it as the best-path. No extra cross-connect required — the upstream is native.

    One port, full blend

    An Internet Port carries the full blend — it includes Cogent Communications alongside the other Tier-1 and regional upstreams. The blend provides the routing benefit of several carriers from a single port, without separate cross-connects.

    Diverse-path egress

    The Internet Port blend egresses over physically diverse paths out of THG1, with multiple Tier-1 upstreams active simultaneously. Single-carrier-incident risk does not take down your egress.
