Sometimes when I nslookup falcon.codes I get this error message:
ssh: Could not resolve hostname falcon.codes: Temporary failure in name resolution
And as I tried to troubleshoot, I saw that somebody suggested to run nslookup -d2 falcon.codes. I ran it, and this is the results:

I can see the server can't find falcon.codes: SERVFAIL message, but I still don't know what to do next. What server failed? What other info does this log give me?
What other commands and options do I have to troubleshoot this annoying repeating problem?
