The first site

Add a site takes a domain — yours or not — and optionally the machine of yours that serves it. Nothing is installed on the target.

Every site gets its preset: HTTP with the full timing breakdown (DNS, connect, TLS, first byte, download; cold and warm; IPv4 and IPv6 where both exist), the certificate, DNS compared against the authoritative servers, and the registration where the registry answers. A site served by one of your machines is also judged on where it actually points: a domain whose records leave your addresses is flagged, not just slow.

Statuses#

up is a site that answers as expected; down is a confirmed failure; degraded is answering with something wrong (an expiring certificate, a missing record). A value that is wrong beyond doubt — an expired certificate — opens its incident immediately; a transport doubt — a timeout — is confirmed before it alerts. Maintenance you declared is shown as maintenance, never as an outage.

Each site's page carries its monitors, its history, its incidents with their evidence, and — when its machine runs the agent — what its own hosting account spends, second by second.
