Of course, anyone further out west ie, europe, asia, aussieland, IS going to lag more. May aswell not bother at all IMO
Your understanding of the way networks function is clearly lacking...
The provider we use for our shards owns private fiber from both the west and east coast at both of which they have points of presence where European traffic will terminate and then ride PRIVATE FIBER directly to our texas datacenter. The only restriction at this point is the speed of light and not internet based routing.
