Anyone else notice a huge drop in CPM?

Hello,
since the 18th of march my CPM dropped from "about 3,50" to "about 1,05" The ads are from the same companies and I see no differences, anyone else notice this?

edit:
I also get the same amount of traffic and the same amount of clicks, basicly nothing changed but my cmp is much lower

 

Not here, only small daily changes.

 

I am testing a new "thing" I redirect the traffic from the homepage to an other domain, there I have the same pages, lets see what the cpm becomes

 

Wow, its up for half an hour now and I see my cpm jumpin from about 1,05 to 4,5
It is a bit early to make sure it stays but it looks good/strange

Yes, I noticed a huge drop, too. I was getting some nice click-through's every day and then all of a sudden it's like it fell off the cliff. It's getting better, but slowly

No it wasn't my CPM ranks but it's my traffic drop down significantly,so i must find another prey
