What's that dip?
If you see a perfectly symmetrical dip in your subscriber data with a net change of (about) zero subscribers, this probably means that the served feed changed during that period. When this happens, you "lose" subscribers from your old feed to your new feed; after you verify ownership of the new feed, you "gain" all the lost subscribers. When this happens, you don't need to worry or do anything; it's just an accounting blip.
