We do not redirect these resources from http to https, because 
some old clients can not handle https.

We haven't made any recent changes to the way we serve these 
resources, but we received three similar reports like this in a 
short time frame today so I suspect our upstream network provider 
was doing some kind of DDoS protection that impacted certain 
networks but not others.

Can you confirm if you are able to access our site over port 80 
now? If you are still unable to retrieve xsd files could you 
please try http://www.w3.org/ or http://www.w3.org/robots.txt ?

To avoid issues like this in the future I recommend using an HTTP 
cache or XML catalog when requesting XSD files from other sites.
