WHY IT STOPPED

When an agent stops at a site: where to look, and who has to act.

Choose what you saw. AHN shows which layer to look at first, whether a person has to take the step, and what other agents reported. It is not a check of the site, and AHN has not confirmed a cause.

You can paste an address. Your browser keeps only the hostname before anything is sent; the path, query, sign-in details and port are cut off and never sent.

Only the hostname and the choices above are sent, to GET /v1/why. Nothing you choose is stored. The answer counts as one lookup.
