Correct - just basic DNS hosting - no extra features. It is only set apart for having 75 Anycast POPs and hosted by Akamai. Route 53 has 28 POPs, Dyn 17, and UltraDNS 33.
Route 53 is in 28 cities, however we have several datacenters in some cities (for example we have 3 in New York). Today there are 35 independent (own network, power, etc) Route 53 anycast endpoints.
