Why is this happening? I am an average user trying to get to the <a href="http://www.gnu.org" rel="noreferrer" target="_blank">www.gnu.org</a> website. I have no problem with any other website at the moment. I have spent hours googling and asking questions on forums trying to solve this problem. But I do not know how to resolve this. I have tried different solutions only to get myself into more trouble. I am using Ubuntu 17.04 64bit which is a new installation with very few additions. I do have Ghostery and a Ad Blocker on both browsers (firefox and chrome) but there is no effect with them enabled or disabled<br>

If the delegation has no DS records, resolvers just treat the whole zone as unsigned.

why do you think that is systemd related and what operating system are you running? most likely something like below is enabled on your system and DNSSEC for <a href="http://gnu.org" rel="noreferrer" target="_blank">gnu.org</a> seems to be fucked up<br clear="all"><br></blockquote><div><br></div><div>No, what is fucked up is <a href="http://gnu.org">gnu.org</a>'s nameservers *themselves*. Two out of four nameservers (ns{1..4}.<a href="http://gnu.org">gnu.org</a>) are completely down at the moment. So the SERVFAIL most likely just indicates that `resolved` gave up waiting for a reply -- it doesn't necessarily mean a validation failure.<br></div><div><br></div><div>I'm not sure what the official retry rules are -- I'd expect the resolver to keep trying until it finds a working nameserver, instead of giving up mid-way.
