Given that you’re having issues with the DNS, I’d look at this.
Specifically, are you using the ISP DNS as an upstream lookup, or have you configured another DNS as the upstream?
Is the ISP DNS locking you out because you’re hammering it?
Does the ISP block traffic on Port 53?
When you’re having issues, can you look up addresses using a different DNS?























Yeah … that’s never going to happen.
