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? Masataka Ohta
