Feedburner - Drop in Subscriber Stats

Drop in subscribers from 6/21/13 to 6/22/13

Client has 3 RSS feeds in Feedburner, and they saw a drop in subscribers from 6/21 to 6/22. Wondering if anyone else has saw a drop recently and if there may any issues with Feedburner tracking?

Most of my feeds showed an increase in subscribers over the same period. The tracking seems to be working fine for me.

I appreciate that, Bill!
