could chime in.

to Virginia to either California or Europe. A
I have notified people who is working on this.

It sounds like you are asking about Geolocation, when what you really
want is latency-b

I don't think anyone believes round robin DNS records is better. It's
that attempting to do better requires adding onto or changing
standards that must maintain backwards compatibility a

You need something more sophisticated than that because for a single
