There are some reports via WebmasterWorld that Ask.com has completed some type of search update.
It is hard to tell for sure, since the volume of traffic received from Ask.com is typically low. So any increases and decreases, percentage-wise, can be huge.
I reviewed a few of my sites and did see spikes up or down via Ask.com from this week to last week.

Been watching movement with ask.com for the last couple of days and my sites been getting progressivly worse as the days move on..
The Ask serps have been before the update very stable and constant.. Yesterday and Today not so much..
But as I said, it is hard to know for sure, like with a Google or Yahoo update.
