Hi,
Something seems wrong with the DNS of 'tools.ietf.org'.
Can anyone conform?
It works for me.
It works for me.
works for me too but there do appear to be some problems:
And what about this:
dig tools.ietf.org @merlot.levkowetz.com.
; <<>> DiG 9.7.0-P1 <<>> tools.ietf.org @merlot.levkowetz.com.
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 33101
Yes:
Finding name servers for tools.ietf.org in parent zone
Checking serials for tools.ietf.org in:
cabernet.levkowetz.com
Query Error: SERVFAIL on merlot.levkowetz.com
shiraz.levkowetz.com
Checking zone NS set against parent
Query Error: SERVFAIL on merlot.levkowetz.com
Error: parent has:
cabernet.levkowetz.com merlot.levkowetz.com
shiraz.levkowetz.com
But tools.ietf.org zone has:
cabernet.levkowetz.com gamay.levkowetz.com
grenache.levkowetz.com merlot.levkowetz.com
shiraz.levkowetz.com zinfandel.levkowetz.com
Also, as others pointed out, there does not seem to be an address for
grenache.
It's generally a good idea when asking this sort of question -- especially
here on NANOG, which is *not* Junior Varsity -- to present what you *expected*
to see, what you *saw*, and why you think that implies breakage outside your
facility.
Let me refer you to:
http://www.catb.org/~esr/faqs/smart-questions.html
and
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html
which are the two standard reference works on the meta-topic here at hand.
Cheers,

And what about this:
But two name servers, gamay and shiraz still work. So the domain
works, so you can email the hostmaster 
Actually it didn't resolve at all. Even an 'unbound-host -v -d' failed.
But... things seem to be working fine again, at least to the extend that I can reach the website.
I have forwarded this thread to Henrik Levkowetz
