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? itojun
