Hi,
I upgraded my PowerDNS servers yesterday to the latest alpha to fix an
issue with memory, the upgrade has fixed that. It looks like after
upgrading from alpha2 to 0.0.910ge143fd4-1pdns.jessie I can no longer
resolve subdomains on protection.outlook.com. As an example:
; <<>> DiG 9.9.5-9+deb8u6-Debian <<>> @10.254.1.10 a
swivelpole-com.mail.protection.outlook.com
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 26622
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:
;swivelpole-com.mail.protection.outlook.com. IN A
;; Query time: 1080 msec
;; SERVER: 10.254.1.10#53(10.254.1.10)
;; WHEN: Tue May 10 10:00:27 AWST 2016
;; MSG SIZE rcvd: 71
This problem has seemed to pop up recently for other people too, see the
bind-users and mailop mailing list:

Short of going back to the other version with memory issues, is there
any config I can add/change that will possibly help with resolving these
names? I can't reproduce this on my other DNS servers that are running
Unbound or on the older PowerDNS recursor instances.
If its helpful, I have put a sample of the trace output here:

Thanks
