APNIC dns glitch ?

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
