Resolver issue, not sure how to diagnose
-
Hello,
I have a PfSense 2.3.2 deployed in an office, and all is good up until now.
This morning, the resolver stopped resolving for a lot of domains. In this list are:
kijiji.ca
the-drive.com
They just go "DNS Request Timed-out" on my nslookups.
I switched the configs to the Forwarder (to Google's and Level3's DNS) and all works well now.
There are no resolver-related issues in the System Logs.My question s: Is there an issue with the resolver/top name servers in effect? And also, where should I look to diagnose what went wrong here?
Thanks

Perhaps, yes!
It makes a lot of sense.
