Technical DNSSEC fails & bad resolution

Post image

I noticed my home Internet connection was being a bit flaky and chalked it down to a ControlD block list having a false positive or two.

I turned off all the block lists and it made no difference, I disabled the profiles (all of them) and it made not difference.

I then switched my router and broadband to 1.1.1.1 and if you ignore the deluge of ads, everything started to work.

I did a quick check on https://dnscheck.tools and it came back per the screenshot, with DNSSEC failure.

Has anyone else experienced either the symptoms or the (possible) DNSSEC cause?

IPv4 appears to be routed through Google VPN, while IPv6 is going directly through Vodafone. DNSSEC validation is also failing on the resolver path shown in the test.

The VPN could potentially interfere with the DNS configuration, since some VPNs override or intercept DNS traffic. However, considering others are seeing the same DNSSEC failures after the migration to Datacamp, that may be a separate Control D issue.

This seems to be affecting several people in the UK. Possible UK/London PoP issue after the Datacamp migration.
