Original Summary

I have had DNSSEC verification enabled for a couple of months in systemd-resolved. Not that I am particular paranoid or do any nuclear-sensitive stuff on my machine. Don&#x27;t even own any Bitcoin. But mostly out of technical curiosity.<p>Until yesterday I had only noticed 2 broken sites (or sites affected by buggy systemd-resolved implementation as some voices claim). Some Jira Plugin and Swedish Railways SJ.<p>Yesterday basically the Internet stopped working for me. After a while I remembered good old operator wisdom &quot;It&#x27;s always DNS&quot;. And it was DNS. Systemd-resolved logged &quot;missing-key&quot; for basically every query I tried.<p>So I switched from DoT 1.1.1.1 @Cloudflare to DoT 8.8.8.8 @Google and life continued. Until today that suddenly out of nowhere showed the same symptom.<p>Turning off DNSSEC verification avoids the problem. An internet search brought up https:&#x2F;&#x2F;github.com&#x2F;NordSecurity&#x2F;nordvpn-linux&#x2F;issues&#x2F;1853 which also links to another one. The timing seems to match with my observation, but I don&#x27;t use NordVPN. Any clues?
