Google Feedburner, true or false, now or then?

It's interesting to note FeedBurner is reporting far fewer subscribers today, down from constant 3000'ish to 760. I wonder if it's wrong now, was wrong before or have I really annoyed lots of people today?

I hope it's a Feedburner problem!

UPDATE 2010-05-21: Not sure it’s a problem but this FeedBurner Blog post explains it.
