DNSimple's origin name servers answer a quarter faster at p90 after erldns work

dnsinfrastructureperformanceerlangopen-sourcedomains
◆Current state
DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.
◆Where it's heading
Since owning its full DNS edge, DNSimple has turned to measurable performance work on erldns and dns_erlang, published openly. The product layer above, CLI and API clients, is moving more slowly.
◆Prediction
Expect more erldns and dns_erlang performance posts; the entries show no sign of a new customer-facing product soon.

    Lower latency on our origin name servers

    erldns changes cut p90 query time by about a quarter, about a third for DNSSEC, and remove a brief window where updated records could return not found. It turns October's library-level gains into numbers customers notice.

    Faster DNS with dns_erlang ⚡

    Rewritten hot paths in dns_erlang cut CPU per query by 12% and raise throughput by 14% on origin name servers, with long-name compression more than 20x faster. It is the first efficiency result reported since DNSimple finished moving onto infrastructure it owns, and the work also went upstream to Erlang/OTP and Elixir.

    Fully Independent DNS Edge

    DNSimple reports that a three-year migration is finished and every DNS query for customer zones now runs on infrastructure it builds, owns and operates itself. It is the conclusion of a long-running programme rather than a new capability — nothing changes in the product surface — but it removes third parties from the resolution path, which is the part of a DNS provider customers cannot inspect for themselves. The changelog entry is a teaser pointing at a longer engineering write-up.

    DNSimple CLI is now available straight from your browser

    The CLI gains browser-based login, so authenticating no longer means generating an API token and pasting it into a config. It is the follow-on that made May's CLI launch usable without a setup ritual, and it fits the pattern of removing prerequisites rather than adding surface.

    Domain Trustee now available

    ⚡ SPARK

    The release that turned a registry eligibility rule into a paid service line, and the clearest example of the pattern running through DNSimple's year: identify a prerequisite that sends customers elsewhere, then remove it.
