Vert ≥ 99,5 % · orange ≥ 95 % · rouge en dessous. En vue ALL chaque cellule affiche UDP / TCP ; fond ambre = un seul des deux transports répond. cache TTL = durée pendant laquelle la réponse reste servie sans nous réinterroger. Un autoritaire KO pendant que les résolveurs répondent = ils servent depuis leur cache, les utilisateurs ne le voient pas encore : c'est la marge dont on dispose pour réagir. Sauts mesurés par traceroute, rafraîchis toutes les 5 min ; « ≥ n » = la cible ne répond pas aux sondes traceroute, n est le dernier saut vu.
