add local file to W3C HTML Validation Service (at UK Mirror Service)?

It appears that the primary W3C HTML Validation Service at "
http://validator.w3.org/" is down again today, apparently due to the August
7 power outage in the MIT LCS W3C building.

So I went looking for a mirror site and found one at "
http://www.mirror.ac.uk/services/validator/".

I'm thinking the primary site had the ability to validate a local file not
on a public website.

Does this mirror have that capability as well? I don't see it.
