Why is this happening? I am an average user trying to get to the www.gnu.org 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.
So here is where I am up to:
So many resolv.conf files in different folders /etc, /etc/systemd, run/systemd/resolve, run/resolvconf and so many other places I dont know about. Why is it not mentioned in the manual pages how to configure them manual or automatically? So many people have different ideas on how to correct this problem online that my head hurts!I have change one file at /etc/systemd/resolv.conf without any effort on the problem. Set DNSSEC=off and added google DNS servers.
Now I will show you the output I am currently dealing with, for which I do not have an answer to.// Where is this config status stored??? In /etc/systemd/resolv.conf ???
$ systemd-resolve --status
