I can detect the problem being in Dallas (dfw), however this is not shown in my results. This is not regular behavior.
If you used MTR to come to this conclusion your understanding of what MTR is is completely wrong. Not sure how many times I need to tell you, or why you won't listen but Server4You is just poor with poor quality, slow routing. Look how inconsistent your latency is
If you're stuck on St. Louis being the best location for you PM me and I'll show you a better provider for the same money, otherwise w.e., back on topic.
We hope to have a few cool new features released today or tomorrow, keep checking back!
