Looks like they host DNS on both cloudflare and akami, but zone contents
are different on the two platforms:

 bjorn at miraculix:~$ for s in $(dig +short ns authorize.net|sort); do echo -n "$s: ";dig +short login.authorize.net @$s|xargs; done
 a10-64.akam.net.: login.authorize.net.cdn.cloudflare.net.
 a1-190.akam.net.: login.authorize.net.cdn.cloudflare.net.
 a2-65.akam.net.: login.authorize.net.cdn.cloudflare.net.
 a9-64.akam.net.: login.authorize.net.cdn.cloudflare.net.
 ns0090.secondary.cloudflare.com.: 104.18.8.127 104.18.9.127
 ns0210.secondary.cloudflare.com.: 104.18.9.127 104.18.8.127

Interesting enough the serial number is consistent though:

 bjorn at miraculix:~$ for s in $(dig +short ns authorize.net|sort); do echo -n "$s: ";dig +short soa authorize.net @$s; done
 a10-64.akam.net.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300
 a1-190.akam.net.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300
 a2-65.akam.net.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300
 a9-64.akam.net.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300
 ns0090.secondary.cloudflare.com.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300
 ns0210.secondary.cloudflare.com.: ns1.dnsvisa.com. premiumdns.support.neustar. 2019103361 600 300 1209600 300

I wish I could say that this is surprising....
