Typically it depends on where they host their server. My hosting company hosts our server in multiple locations across then US so there isn’t as much of a lag. That’s pretty typical these days for all hosting companies. The largest being Amazon.Actually, there is something to that. Some investor companies paid billions to have the shortest fiber runs to the stock exchanges years ago and at some point the men in black required all fiber runs to be the same length, so they took the really short ones and looped fiber around and around to equal out the runs. Crazy stuff.
