Yeah, currently I run my own DNS server. However, as traffic grows and so does your customer base and server locations, it would be nice to use a dedicated DNS provider, as they'll already have the infrastructure set up to handle a significant capacity of DNS resolutions quickly, as well as servers around the globe to do so efficiently. In addition to the speed, it's usually also less expensive than setting up and maintaining multiple DNS servers of your own around the world.
