    Nope. Run your own recursive validating resolver, like unbound, with DNSSEC enabled and enforced. Don't contribute to surveillance capitalism.

    NEVER use your ISP's DNS, ever. Suggested Options: • Cloudflare DNS: 1.1.1.1 and 1.0.0.1 OR • Google DNS: 8.8.8.8 and 8.8.4.4

    AHH, my employer forces me to use a MITM TLS-Proxy () for my daily work. Firefox is completely dead now because of HSTS. F*** off. Any hints on how I can override the locked Proxy settings?

    Probably this bend was the problem. Mäh. This was the first time I've seen a real-world problem in which the basic cabling tester did NOT tell the truth.
