*** UPDATE *** Everything is fine. YT is back up.
Magic Martin and others have alerted me to the fact that where a youtube video should be sitting comfortably on my site there is instead a large white piece of uninhabited real estate.
This appears to be world wide and not focused on any particular group of web sites. (ahem ahem)
A google search turned up this forum of freaked out people. It will probably be fixed pretty fast. There are buckets filling with sweat over at google, I am guessing, by now.
Seems ok now
