Utilize an algorithm to identify the "misses"

Farsight found that the level of misses grew by four to seven times at the end of March and the beginning of April, creating an increase in traffic volume.

Shouldn't we be able to create an algorithm or worm to check DNS servers (process that runs throught all of the A records to validate proper responses, if after a period of time, an emaail can be sent out to the owner of record to have this "error or miss" corrected or removed (automated process).

Python offers some nice modules (import dns.query, dns.resolver, dns.update, dns.tsigkeyring)

This process could run all the time verifying the date, time and name resolution status after a specificed period of time.

This could be used as an alternative to A DNS records that are invalid or a "cache miss".

Cache
Because most Internet users visit a limited number of sites, DNS caches help to efficiently handle popular requests. I agree cache will reduce the traffic in DNS recursive requests.

Re: this is definitely a case of x - where x is a veriable
Increases in bad requests could be the result of malware combined with some cheeky DNS bit squatting. I agree. It may as well be a miss configuration of DNS records.

DoS
such as misconfiguration or a change in behavior as people started working from home Yes, these all result into more DNS request I would say. Or it may be DoS attack.

this is definitely a case of x - where x is a veriable That is good point. X being variable it adds more complexity to it obviously.

DNS
An analysis of domain-name system (DNS) requests for 316 major sites across five industries shows a massive.. Good opportunity to be online more than before so good opportunities to plan security intrusion as well.

If its DoS its not a very good denial of service. Maybe these sites have been studying the dark arts and found legal but nasty ways of driving traffic to them. Increases in bad requests could be the result of malware combined with some cheeky DNS bit squatting.
