My website backlinks decreased month over month for 3 campaigns what is the reason?

My link metrics have decreased for several campaigns, loss of links range from 500-1500. Why is that ? Is there a new update or something that would cause this issue? I find it weird that three separate campaigns would decrease in external links when we have not done anything to remove links on our end.

Hi Karen. Yes there was a recent update, please read about it here: http://moz.com/products/api/updates (that's the home of API update news btw).  And here's the Q&A post discussing the specifics as to why link numbers fluctuated: http://moz.com/community/q/have-questions-about-the-jan-27th-mozscape-index-update-get-answers-here.
