- Best for (20 words max)
- Estates wanting a global IP network, with an MPLS style private network as a secondary offer.
- Review date (YYYY-MM-DD)
- 2026-10-06
- Strength 1 (25 words max)
- Operates one of the largest IP networks, with NOCs in Washington D.C., Herndon, Overland Park and Madrid.
- Strength 2 (25 words max)
- Lists UK PoPs including London, Manchester, Edinburgh, Glasgow and Belfast.
- Strength 3 (25 words max)
- Names an SD-WAN overlay.
- Weakness 1 (25 words max)
- The only SLA text found is a 2006 copy, so no current availability, latency or loss figure is recorded.
- Weakness 2 (25 words max)
- No UK based NOC or 24x7 NOC statement was found.
- Weakness 3 (25 words max)
- No SD-WAN platform or SASE platform was found.
- Buyer size fit (comma separated: Large global enterprise, Mid-market, Small business)
- Large global enterprise
- Verdict (40 words max; must include one figure from the fact sheets and the review month)
- Netify would consider Cogent where a global IP network matters more than MPLS detail, with UK PoPs in five cities and four NOC sites. Its only SLA found dates from 2006, so ask for current terms. Reviewed October 2026.

- Notes
- Legal name and number are a Companies House name match only. Contracting entity, parent, type, URLs and Ofcom status not yet reviewed. Added from the current Netify page. Re-check 2026-10-02 (page-reader wording, confirm on the page): the outside pass cited the Taiwan MPLS page; the English MPLS IP-VPN page exists and is used. The SLA PDF covers MPLS IP-VPN as well as internet and Ethernet: 100% availability and 99.9% packet delivery (entered as 0.1% loss, a published target), with 45 ms or less in North America and 35 ms or less intra-Europe, not 90 ms. No UK-only latency is published, so UK core latency is left to review. The Bristol address is the registered office only, so NOC and UK support cells are left out. The Companies House PSC is Cogent Communications Holdings, Inc. directly. Cells filled on 2026-10-02 from the outside research pass are Partial unless the re-check confirmed them. Not found means the pass searched and saw nothing, not that it does not exist. Verify each against its source row, then set Decision.
