RPKI ROA depth · New Zealand (networks)
What is the rpki-roa-depth of networks in New Zealand?
40.19% of networks in New Zealand are few roas, measured across 428 networks on 2026-10-01. This is a composition measure, not a failure rate.
Measured every Sunday since 2026-08-01 — 3 observations to date. Last measured 2026-10-01.
How this is measured
bulk feeds only — no network is probed. The ROA count already carried on each ASN's census row from the RPKI validated payload, banded: none / single / few (2–9) / many (10+). Population unit: ASN; segmented by country and RIR.
Built entirely from public bulk feeds — no target is contacted. Aggregate-only. 95% Wilson confidence intervals. Population: networks observed announcing at least one prefix in RIPE RIS, attributed to a country and RIR from the RIR delegated files. Snapshot: rpki-announcing-asns.

Why it matters
rpki-roa-coverage answers yes or no, and the yes hides a range. A network with one ROA has done the hard part — the RIR portal, the key ceremony — and is recorded as covered, while any prefix that ROA does not cover still validates as not-found, exactly as if nothing had been published. The shape of the distribution is where the adoption story actually is.
Limits of this measurement
A ROA count is not prefix coverage, and this metric must not be read as one. Proving a network's announcements are covered needs the full RIS prefix table joined to the VRP set; that is a different measurement and is not made here. A single ROA covering a network's only prefix is complete coverage; a single ROA at a network announcing fifty is not — from the VRP dump alone the two are indistinguishable.
