IP Blocked By http://validator.w3.org/

Hi,
I'm hoping you can assist me.  I am the network admin for MathWorks and I have been told that our developers use your tool at http://validator.w3.org/..  For some week we have not been able to access your site because our NAT address, 144.212.3.4 seems to be blocked by your firewall/site.  We have a large number of developers here that all come from that one IP so it may look like an excessive amount of traffic from one IP but this legit traffic.  Could you please open up access from our public NAT address once again?

Thank you,
Mark Burke
