Looks like businesses are seeing that they have lost +1's on their Google+ page overnight.
This Google product forum confirms the very recent hit to pages: http://productforums.google.com/forum/#!topic/webmasters/zKsjyJ620cI
A user on this forum stated possible causes:
1. Never use 1 ip to vote all the +1s for your website.
2. Never use same accounts voting 5 different sites at the same time. This looks suspicious for google.
3. Google has a bad habit of removing accounts if they are kept inactive for a long time. This can lead to removal of plus +1s.
If you have a business page, have your +1's taken a hit?
Let's troubleshoot together to see if there has been a Google+ update. All thoughts and comments are welcomed!
