Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
check_contact_pathGiven a business website URL, report how a human is meant to make contact and whether that path is actually reachable. Returns a verdict of 'reachable' or 'inconclusive', the forms found with their resolved handler URLs, and any published phone or email. Never submits anything. Answers 'inconclusive' rather than guessing when a site is client-rendered, bot-protected or parked -- about 64% of real sites cannot be judged from outside, and a confident wrong answer is worse than an honest one.

Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
