Cannot access validator.w3.org

I cannot find any better place, so I'm writing here.

The site validator.w3.org is functioning properly, but I cannot access
it from 193.87.79.99. It's address of our school server www.gjh.sk
with many computers behind NAT.

So please consider inspecting the firewall for that address.
Thank You
