So it's not just me who is seeing a problem. I have tried to reach Jan Žorž through a couple of different channels to let him know his NAT64s are down. I suspect that page may be hosted on the same network. I suppose I should look for some contact information for Sander Steffann to let him know his page is also down, and maybe he knows how to get in touch with Jan Žorž.
