I think you're mistaken about the server being off-line, since I can see
it just fine from many places. The RIPE NCC dnsmon tool can also see it

I did (and do) check on multiple ASs that I run and asked a few others to
check, also checked looking glasses and so on.

So, out of curiousity, i loss of 1 of 13 gtld servers important? I believe
(though I could be mistaken) that these are actually anycast as well. I
think dropping even 2-3 of the servers probably wouldn't affect overall
performance would it? won't bind pick the 'best' place to ask regardless
and stick/prefer that over 'slow' servers?

I think he was right to report it here - its operational issue with very
large TLD. But it is certainly nothing to seriously worry about as dns
compensates for such problems.

 Ooops, sorry, I didn't mean to harangue Will for reporting it, I was
asking if it was in fact not a big deal because the system has
compensation methods in place to deal with even 2-4 device outages.

sorry for the confusion.
