- Notes
- From the provider legal notice. Companies House record not yet checked. Added from the current Netify page. Re-check 2026-10-02 (page-reader wording, confirm on the page): Companies House shows no active PSC, so the outside parent (Zayo Group Holdings, Inc.) is not supported. The IP VPN page confirms Layer 3 any-to-any on an MPLS core; the overview PDF gives up to 99.99% core availability and 6 QoS levels, not UK specific, so neither is entered. Coverage relied on a directory page (Tier 4) and is left out. Managed SD-WAN and SASE pages name VeloCloud, Fortinet, Versa, Palo Alto Networks and Netskope. Sector pages have no named customers, so sector cells are left to review. 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.
