Is there any service which is 24x7 DNS A and MX record lookup'ing the Alexa top 10,000 websites from multiple countries, and recording changes in a log? If not I think this might need building.

So you can probably see the issue here, if there's multiple constant lookups going across big sites across lots of DNS servers, it should flag manipulation.pic.twitter.com/PplyG9BYX6

what about DNS zones' negative cache/TTL and various awkward related settings different resolvers implement?
-
you just have to account for that, e.g. if somebody had looked up Google DNS for this they would have spotted the shift

How would this work with CDNs though? You'd expect to frequently get different results. Perhaps notify on change of netblock owner for target?
-
you could cater for it, e.g. if you know what it usually looks like (historic logging) and it suddenly changes to a different netblock etc. Or just plain log it.

I wrote a powershell script that can do this, multi-threaded Dns Over HTTPS.pic.twitter.com/TM06YJnu9Q

My idea would be a bunch of lambda functions spread across AWS regions, that write into a single DynamoDB. (Or to files and then to DynamoDB) And an API that exposes data in the DB for public consumption. Sounds costly though. But I’m happy to help build out
