@stompro said in Insanely weird issue with DNS resolution to www.cdc.gov:
seems like a fad, like fidget spinners
Not sure if I would say that - but the overall adoption is disappointing to be sure..
Here is the thing that site is all kinds of messed up when it comes to dnssec... I don't have any problem resolving it, using dnssec - but with some of the errors I see, it could for sure be hit or miss.
If your forwarding, and also have dnssec enabled that can cause issues. So are you saying when you uncheck dnssec in unbound, and forward to cisco it fails? Is that something you have to enable do disable in your subscription.. Cisco Umbrella is a subscription service is in not?
