What is Contour?

Three supported branches, patched in lockstep within the same minute.

Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.

What is DNSimple?

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

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.

Contour vs DNSimple: editorial side-by-side

C
Contour
INFRA · APIS
0.0

Three supported branches, patched in lockstep within the same minute.

◆ Current state

Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.

◆ Where it's heading

This is a proxy whose release cadence is governed by its data plane rather than its own feature work. Envoy security releases set the schedule, and Contour's job is to bump, verify compatibility and ship across every supported branch simultaneously. The changes that do originate in Contour are operational sharp edges found in production: an HTTPProxy CRD schema wrongly marking a status error field as required, which broke load balancer status updates, and shutdown-manager being CPU-throttled at a 50m limit.

◆ Prediction

The next release will almost certainly be another simultaneous three-branch batch triggered by an Envoy security bump, since both batches in this window followed exactly that pattern.

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

◆ 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.
