Expected result
Unblocked websites to resolve properly.
Actual result
everything from Google to personal DNS records resolved to 0.0.0.0

What does the query log show?
Looks like everything was getting flagged by the Anti-Malware filter.
it brought down the whole network till I turned off filtering. I changed the DNS to a public DOH server in my router for now.

It's not a good idea to use the malware/security filtering anyway as it adds significant latency to requests.
You'd be better off using an active and maintained malware blocklist instead

I thought that's what it was referring to, the Anti Malware list here that has 25k entries.
Ah ok. So it was a list.
There must have been an errant entry in that list that was black-holing everything then.
