Anyone else's imports via SFDC app dropped drastically in recent days?

I was running reports for our previous month's email performance and I noticed that our email sends were really low. In checking the SFDC app the number of imports is all over the place but far below what the number normally is.

For example one of our campaigns that supports a large partner hasn't had a contact meet the segment criteria in 8 days. The segment has two criteria, so it isn't complex. The segment hasn't been edited in months so I'm not sure why contacts aren't meeting the segment criteria/entering the campaign. Any thoughts or ideas?
