Authoritative DNS Latency

A fixed vantage point queries each authoritative DNS provider directly on a schedule and records round-trip time and whether an answer came back. The numbers are measured from that location and describe only that place and time; rows are sorted by the 24-hour mean of all answers, click a row to see each address.

Method
  • A SOA query goes straight to every NS address, without recursion. Only NOERROR counts as an answer; no reply is a timeout; any other reply is a refusal and is left out of the answered rate.
  • One round every 5 minutes, 5 queries per address per round; every answer counts separately.
  • Stats cover the last 24 hours. Mean = average round-trip of all answers; P90 = the round-trip that 90% of answers are no slower than, not the slowest one; latest = mean of the latest round; answered rate = answers ÷ queries sent. Timeouts affect only the answered rate.
  • A provider row pools the answers of all its addresses; at vantage points with a query share it is weighted by that share.
  • NS addresses are resolved by public resolvers common in the vantage point's region, at most 4 per name per protocol; an address not seen for an hour is dropped.
  • Each provider is queried for a domain it hosts itself, shown when expanded; ClouDNS is queried for who.sb on its free tier.
  • Every round also checks two baseline targets; a round where the baselines mostly fail is discarded.
  • Query share: each vantage point also runs a default-configured Unbound that resolves every provider's domain 20 times per round, recording which address it queried; share = queries to that address ÷ queries to all of the provider's addresses.
  • After each address: country or region (GeoLite2) and attributes. anycast = nodes in many places, no region shown; accelerated = addresses of this site's lines toward mainland China; no tag = a single fixed-location server.

Location tags use GeoLite2 data created by MaxMind, available from maxmind.com.
