Services

Cogent Communications Solutions

IP transit, dedicated internet, Ethernet transport, wavelengths, and colocation — delivered over one of the most interconnected Tier 1 backbones in the world.

Dedicated Internet Access (DIA)

Symmetrical, uncontended dedicated internet circuits delivered directly on Cogent's fiber backbone. Available from 100 Mbps to 100 Gbps with SLA-backed uptime and latency guarantees. Cogent's on-net building footprint in thousands of commercial properties enables direct last-mile fiber delivery without third-party local loop costs.

IP Transit

Carrier-grade IP transit for ISPs, cloud providers, and large enterprises requiring high-volume internet bandwidth. Cogent peers with every major Tier 1 provider globally and delivers full BGP routing tables. Ideal for enterprises operating their own IP infrastructure or requiring multi-homed redundant internet at scale.

Ethernet Transport — Metro & Long-Haul

Layer 2 Ethernet transport connecting enterprise locations, data centers, and carrier facilities across Cogent's fiber network. Metro Ethernet for campus and city-wide connectivity; long-haul Ethernet for coast-to-coast or international point-to-point circuits. Available in E-Line (point-to-point) and E-LAN (multipoint) configurations.

Wavelengths

Dedicated optical wavelengths (10G, 100G, 400G) over Cogent's DWDM backbone for enterprises requiring maximum bandwidth with minimum latency. Used by financial services, media, and hyperscale workloads that need predictable, uncontended transport between specific points on the network.

Colocation

Data center colocation in Cogent-connected facilities across North America and Europe. Direct on-net access to Cogent's backbone from colocation space eliminates cross-connect fees and reduces latency between hosted infrastructure and the internet. Rack, cage, and suite options with redundant power and cooling.

DDoS Protection

Network-layer DDoS protection delivered from Cogent's upstream backbone — traffic scrubbing at the edge before attacks reach customer infrastructure. Volumetric attack mitigation at scale without requiring on-premises scrubbing appliances. Available as an add-on to DIA and IP transit services.
