This fixes the false positive we got on the NixOS Infra Alerts channel today.
It also adds an alert for when a whois query fails for more than three hours. I chose three hours as a heuristic based on the duration of previous failures of this probe, so that we don't get false positives when there's a blip in a WHOIS server.
