Provider, certificate, registration and reachability moves that matter, distilled from every scan in the last 24 hours. This is the day, in one number.

448domains changed DNS provider

Who runs resolution. A DNS move re-homes all of a domain’s traffic, and it is usually the first public sign of a re-platform.

EMAIL DRIFT▲ 84 vs yesterday
92domains switched email provider

Where the mail goes. An MX move changes which company receives every message sent to the domain, and migrations show up here first.

CERT DRIFT▲ 140 vs yesterday
163domains switched issuing CA

Who vouches for the TLS handshake. CA switches track CDN moves and platform changes, and a surprise switch on a domain you own is worth a look.

NOT ANSWERING▼ 951 vs yesterday
1,759curated domains gave no response

Silent on the last probe: nothing answered at all. The composition says why, and movement against yesterday is the incident signal.

1,419 timed out·340 DNS failed
ERRORS
20,885responded with an error

These answered, but with a problem: an origin serving 5xx, a missing root document, or a TLS handshake that fails.

11,955 5xx origin error·8,930 404 at root
THROTTLED
92,891throttled or blocked our scanner

Healthy sites that rate-limited or bot-blocked the probe. Not an outage: a bot-defense posture signal, mapped across the catalog.
