Yes, but magicians always use tricks.
I've got a few dozen servers with MTU 7500 that aren't
having a bit of trouble talking to anyone.
Your trick is that your routers at the border between MTUs
7500 and 1500 (or maybe, 1400 or so) generate ICMP packet
too big packets to your servers and no intermediate
entities filter them, isn't it?
