There could be a lot more reasons than that, I think.
Bear in mind how very tightly connected AdWords and AdSense are - heck, whenever they take one down for maintenance, the other one has to go too (BTW - AdWords maintenance this Saturday, so AdSense will no doubt be down too) So when reports lag, or there's a problem logging in, or it temporarily goes offline for a few, I bet sometimes it's totally something happening on the AdWords side, and not necessarily anything to do with AdSense. And vice versa.
And for all we know, possibly Google Analytics and other products could be affecting it as well. Heck, the whole Google account system, for that matter.
I suspect that whenever the system gets behind, eg having to do the extra work behind PIP, or should a ... ahem ... bug ever happen, then everything suffers until the backlog is cleared.
Yes, I imagine much of the work happens using the same MapReduce-et-al framework and CPU pools, and G won't want to have too many spare most of the time as its a waste of capital, space and energy.
Good we can make a list then:
1- Code maintenance
2- Click fraud auditing
3- AdWords maintenance
4- Resource redirection e.g. PiP calculations
I would also like to add a couple:
5- Updating the per account SmartPricing variable
6- Re-adjusting traffic conversion probability
(e.g. seasons, event spikes, country specific, topic specific..)
I'd like to add:
7- Find and kill MFA
. o O (may be in my dreams)
8- The folks at Googleplex intentionally hold the reports back and bet on which WebmasterWorld member will be the first to start an "updation delay" thread :)
Yes, yes, #8 has my vote rocker!
You win today's star prize which is a private updation delay and/or a tax audit. You'll only work out which when you recover from the surgery within the witness protection program (and you still won't be allowed a new AS account)! B^>

ROFL, and in all honesty I really have wondered whether they actually do this?
I know how we could stop them...have a permanent "Updation Delay" sticky at the top of the page!
9. Replacement of equipment and failure to back-up/transfer data.
With so many servers they must be replacing lots of them on a daily basis?

Yes, but the data and calc is distributed in such a way as a failure and then a hot swap of a bit of kit won't lose anything or require any explicit movement of data or computations before or after.
i don't know what's happening but adsense site was down about 5-6 hours (maintenance?) and now is working again but stats are the same as 5-6 hours ago :S
somebody have same problems?
sorry for offtopic ;)
