KMZ files can contain fibre lines, facility points or coverage areas. The files below identify what each source actually provides.
| Carrier | Available data | Access |
|---|---|---|
| Zayo | Public metro and long-haul fibre KMZ dated 15 March 2019. Its Canadian long-haul geometry includes Peterborough; positions are deliberately generalised.[111] | NCTC download links ↗ Explore the HTML map ↗ Download fibre KMZ ↗ Zayo’s Canada–US overview also describes detailed KMZ access through Tranzact.[110] |
| Arelion | Detailed wavelength-route KMZ supplied case by case under NDA. Its AS1299 record lists regional interconnections including Toronto, Montréal and Buffalo.[113, 118] | Account-manager request details ↗ Network and plant enquiries ↗ |
| Cogent | Cogent’s optical wavelength product sheet offers route maps, latency metrics and KMZ on request. The public NCTC KMZ contains US facility points.[112, 124] | Route KMZ request information ↗ Wavelength facility map ↗ Wavelength network PDF ↗ NCTC file links ↗ Download US facility KMZ ↗ |
Uniti offers custom KMZ files by request. Its current wholesale map, reached from the former Windstream Wholesale website, shows long-haul routes, metro laterals, data centres and POPs.[115]
Uniti KMZ request information ↗
Segra offers a network KMZ and on-net/near-net building list for its US network through a file-request form.[116]
ISED’s National Broadband Data catalogue includes KMZ map data and provider-road data in GeoPackage format.[117]
Coverage files describe where a provider offers service. They do not establish a local fibre backbone, POP or wavelength route.
Lumen publishes an interactive global network map. It includes owned, leased-access and IRU segments without distinguishing them, and its terms prohibit duplication.[114]
For regional planning, a useful request covers Toronto–Peterborough–Ottawa–Montréal and Toronto–Buffalo, with the required facility endpoints. Ask for the file date, operational and planned routes, ownership or lease classifications, and permission to display the data on a public website. Keep NDA route files out of the public map.
