Feedburner Glitch, or Just Me?

A few days ago I noticed my feed count for two of my websites dropped by about 50% overnight. Assuming that 50% of my readership didn’t suddenly decide to unsubscribe at the same time, I figured this was a simple glitch from Feedburner:

I contacted customer service and posted on the help forum, with no response from either, as expected. This went on for five days, then suddenly this morning the feed count jumped back up to normal numbers. It didn’t jump up again for the other site yet, so we’re yet to see what happens there.

Did anybody else have this issue?
