[Pdns-users] problems resolving 'juniper.net' in 3.1.5?

Have another domain that seems to have stopped functioning:
It appears to not attempt to recurse to the other dns server. Which is ns1.easydns.com. And thus just fails. I did a dig and you can see that ns2.easydns.com fails and thus the recursor fails never trying ns1.

Subject: [Pdns-users] problems resolving 'juniper.net' in 3.1.5?

Hi everybody,

Over at #powerdns on IRCnet we are currently trying to debug a problem where
heavily loaded PowerDNS 3.1.5 recursors are unable to resolve the
juniper.net domain name.

Could 3.1.5 users please try to resolve www.juniper.net, and if they find
that there is a problem, see if you can get PowerDNS to provide you with a

this can be done for example by adding 'trace' to the configuration file,
--trace to the commandline, or by sending signal USR2 to the pdns_recursor

Be warned that this will generate TREMENDOUS amounts of logfiles.
