Is there a downside to using Google's DNS servers?

There were issues in the past (several years) when using a 3rd party DNS server could cause problems with CDN’s like Aakamai, and ones used by Netflix, YouTube, and social media sites. Your local ISP’s DNS server would correctly route your traffic through the local CDN, giving faster loading and download times. However, 3rd party DNS servers couldn’t determine your location and would route traffic through a very far away network, if not the originating server thousands of miles away, rather than the local cache a few miles down the road.

This doesn’t seem to be the case anymore as far as I can tell. I’m curious how that’s been resolved, or at least mitigated.
