The figures I gave assume that all the hardware we have already bought is still in operation (which surprisingly is more or less the case).
What I'm saying is that the hardware you buy today is both a current expense and an investment in the future. The budget figures make it look like it's solely a current expense.
If you're using those cash-basis figures that's another problem with the
model as well :).
Yet the model has closely predicted increased costs for the last year (yeah, to an extent this is self-fulfilling, but only so much so)...

The exponential growth has probably to a large extent made the previously bought hardware negligible, though this will become less and less so as time goes on (even if growth doesn't slow). Along the same lines as the costs being largely self-fulfilling (whatever is allocated in the budget, that's what's going to be spent), I've personally noticed a fairly steadily increasing reliability in the system in the past 9 months or so. I believe it was less than a year ago that Wikipedia wasn't even able to enable search the vast majority of the time. The site is still fairly flaky, but a lot less than it was a year ago.
Anyway, I haven't looked that closely at your model and maybe you've figured out a way to capture this in some other way, or maybe it's just a coincidence that it's worked so far. How many quarters have you actually made predictions using this model (actual predictions, not backing into historical data after the fact)?
If you'd prefer I take this conversation off-list I can do that. I'm not trying to criticise, just make some helpful suggestions; preparing financial statements on a GAAP basis is a large part of what I currently do for a living, after all. The [[Wikimedia Budget]] page mentioned that "The Wikimedia budget has to follow Generally Accepted Accounting Principles (GAAP) for Not-for-Profit Organizations", and GAAP requires statements be made on an accrual basis. Even if you're going to ignore this and use a cash basis, you should at least use a modified cash basis which factors in things like depreciation.
