I thought I'd sent this a couple of hours ago APNIC are aware of the problem and things have partially recovered though the arin and ripe name-servers still SERVFAIL the second run of our delegation-checking script this morning started complaining about our 203.in-addr zones and it seems there is an issue with apnic.net the delegation shows 4 entries spread across 3 domains which is good, albeit all are under the same registry. Sometimes cumin.apnic.net and innie.apnic.net. are not reachable, or give a REFUSED response, or give a response with no A records nor any additional section. Unfortunately both tinnie.arin.net and ns-sec.ripe.net return SERVFAIL, as if they had not been able to perform a zone transfer for a while (assuming AXFR is the replication mechanism). I don't have ipv6 connectivity, but that's not likely to help. I don't think this will significantly impact reverse dns lookups as I think the dns is spread across other RIR's seems there was a different type of issue in May http://www.bauani.org/thinkings/2008/05/issue-with-apnic-dns-nameservers.htm...
