I recommend Akamai Edge DNS because it is distributed globally and prevents DDoS attacks.
Akamai Edge DNS offers stability and security with recovery of deleted zone files, accommodating diverse configuration needs. Its high availability is supported by numerous POPs with global distribution to counter DDoS attacks. Users experience long-term stability but face setup complexity with cloud providers. Pricing is higher compared to competitors like Infoblox, suggesting a need for a better pricing model. Notably, Akamai lacks CNAME flattening support.
