MSN Adcenter traffic surge 22/3 23/3

Has anyone noticed an unprecedented MSN Adcenter traffic tsunami on March 22 and March 23?

Without actually touching my MSN campain, CTR and traffic volume has tripled during those dates (March 23rd being the best day), and overall traffic quality has doubled (measured in terms of clicks/conversions) – a compounding effect of 6x on conversions. I wish I could hold to this traffic forever!

However, the extra traffic stopped on March 24 and traffic is back to normal ever since. Again, without me actually touching the campaign at all. It seems that the extra traffic came from the MSN network membership zones rather than msn.com or live.com searches.

There are rumours that overall MSN traffic has been on an increase for some time now, however this does not explain such surges.

I think this might have to do with the MSN Adcenter team testing various components and ads over the entire MSN network. Kudos for the MSN team! Keep doing some more tests, and give us some more of this sweeeeeet traffic!
