Yes. MIT is one of the three global hosts for W3C and the one handling North America. They host us physically (W3C has office space as part of MIT's Computer Science and Artificial Intelligence Lab) and they host our machines and network.
It may be folks in other parts of the world can get to our servers in other parts of the world, or maybe there's a single point of failure in the current configuration.
Thanks for the info. At the moment, www.w3.org recursively resolves to the same MIT IP address for me from hosts in GB, NZ, and JP, so it looks like there is a single point of failure, at least for the website.
A cool thing about Aaron's activism was that it involved building things, circumventing censorship, and spreading information, rather than sabotage and denial-of-service.
