Dear AdWords [referer spoofing req'd]
I'm getting reports that something major maybe happening with Adwords - the thread above by BakedJake suggests large and irratic jumps in usually calm, predictable stats for larger advertisers.
It may be that a major shift in the Adwords algorithm is taking place, and then it could have something to do with shifts in datacenters that also appear to be happening right now.
And let's not discount the introduction of the Adwords API as if there wasn't already enough to be paranoid about heh...
So, any Adwords guys want to add fuel to the fire or douse it?
