What is a reasonable latency to see on a link of that distance?

You'll want to ask whether this is one-way latency or round trip time.


I'm seeing this from Amsterdam:

I don't think you're going to do significantly better than this, I'd be amazed if anyone can do London - Chicago below 90 ms round trip.
