Thanks for the update that dnssec STILL causes more real world problems than it solves. 

.....

That said, arin is a pro outfit. If they can screw it up, like nasa, so can you. No your threats and deploy wisely

Suresh -

We’re aware and working the problem.  It looks to me like expired RRSIG/DNSKEY’s for the zone, 
so if you’re using a DNSSEC validating resolver (e.g. Google, Cloudflare, Cogent) then ARIN.NET
is unreachable.   ARIN’s engineering team is working on resolution now.
