Noticed with 2024.1 that there are additional cnames - 3 total - when setting up a domain. Is creation of all the cnames now required? What happens with domains setup before 2024.1

According to the 2024.1 release notes, there should be 2 CNAME records now. One is the main domain and the other (_acme) is for the new DNS challenges feature. This only applies for setting up new domains though. Not sure what the 3rd CNAME record you are seeing is.

There is one with verify in it: domain.com.hosting-verify.netsuite.com
