Suddenly this morning, the YouTube videos embedded in our pages (there were 2 on the front page) started causing page loading errors; the server ‘i.ytimg.com’ (a YouTube address that normally serves thumbnail images for the videos) was trying to read a file from localhost, via port 8881. The exact URL of the request: localhost. (The ‘crossdomain.xml’ file is a Flash feature that allows getting around some of their security borders).

It could be completely innocent but I don’t like errors, and there’s a remote chance the YouTube system has been compromised, so I removed the videos for now.
