50% Drop In Impressions - A little Shocked

[zab205]

Over the past 48 hours I have seen a 50% drop in impressions across my campaigns. I have not made any changes. My adwords impressions/traffic/spend has remained very consistent within a small range over the past 6 months. Is this a result of all the changes google is making to adwords this month? Is anyone else experiencing this?

Thanks for any feedback.

I think it would be helpful for you to identify where you are advertising: 1) Google, 2) Search Partners, or 3) Display Network.

I'm advertising across all 3. The drop has been across all 3.

For the GCN, it could be a large publisher has excluded you from appearing on their properties?

As for search I'm not sure what the issue could be.
