It seems as though, this is happening to me as well.
Odd, I used to be able to ping 8.8.8.8 from the controller, now not so much.
I know that google does do IPv6 on dns resolution.
Validated and ipv6 is disabled on my controller so it should resolve on ipv4.
I double checked a few other controllers and none of them can ping 8.8.8.8 or 8.8.4.4 or any IP that google.ca or google.com resolves to.
odd.
