Starting at about 5:15am US Pacific time, Zoho Wiki server started failing to deliver the custom css file that should accompany each page. (And similar result on a second wiki).

Firefox Network Developer Tools chart shows that the page requests

but the Transferred column shows NS_ERROR_CORRUPTED_CONTENT, Size 0B.

This is a css file that has not been recently changed, and has worked fine for many months, if not years.

A second, separate, wiki has the same problem.
