Methodology
viabandwidth is a network-verified directory of physical datacenter infrastructure, operator ownership, and network presence. It tracks 7,847 facilities across 114 countries. This page explains how the data is sourced and verified, what each label means, and what is free versus a paid unlock. Maintained by Steven Higashi. Last reviewed 2026-06-10.
How facilities are verified
Every facility is cross-checked against network evidence rather than self-reported listings. We combine public registration data, internet-exchange and peering records, autonomous-system and announced-prefix data, and operator-domain matching to confirm who actually operates infrastructure at a site. A facility is only marked a verified operator when that evidence holds together. We do not republish a third-party map; the verification layer is independently derived and re-checked on a rolling basis.
Confidence tiers
- Verified operator
- Independent evidence — network presence, ASN and announced-prefix data, operator-domain matching — links the facility to a real infrastructure operator.
- Network-confirmed presence
- Networks are confirmed present at the facility, but operator ownership is not independently proven.
- Public facility record
- A known public facility where the operator relationship is not independently confirmed.
- Discovered facility
- Surfaced through network-signal discovery, with sparse metadata pending enrichment.
Connectivity bands
Each facility carries a connectivity band — Dense, Active, Listed, or Unknown — a verified summary of network density derived from how many networks, internet exchanges, and carriers are present. The band is free; the exact counts and the underlying network evidence are part of the paid operator dossier. The thresholds are deliberately kept private so the bands cannot be reverse-engineered into the raw data.
Free versus paid
Discovery is free: facility name, city and country, an approximate map point, certification labels, verification tier, and the connectivity band. The paid layer is the intelligence that saves procurement and research time — the exact carrier, ASN, and exchange evidence, the operator and facility relationship graph, comparable operators in the same metro, and role-based sales and procurement contacts. Credits unlock bounded, useful intelligence, never a bulk download of the database.
Sources and limitations
Connectivity and operator signals draw on PeeringDB and Regional Internet Registry data, enriched with operator records and our own network analysis. These are signals, not guarantees: a verification reflects the evidence we could confirm at the last review, not an operator endorsement or a promise of live availability or pricing. Facility specifications such as power and cooling are reported where public and may be incomplete.
