no, its not just you. i've had issues with couple customers having problems
visiting two large sites due to pMTUd breakage. it was discouraging to see
some fortune100 web sites breaking their filtering too much over the line.


        in many cases, those companies put web load-balancing device, and
        the device prevents PMTU from working.  maybe identify vendor which
        ships 'drop all icmp6' and teach them nicely?
