because he's getting only 100Mbit/s   of course, if he's paying for
dark fiber (unlikely) somebody is skimping on the tranceivers.

much more likely is that it's a normal VPN setup, where latency can be
anywhere from 3ms if he's lucky to 50ms if not.

in any case, with just 100Mbit/s, traffic shaping is a must.  the
question is who will be doing it, the customer, or the provider.
