A year or so is fine because those issues have been resolved by: - a slower economy (I'm putting this here because we shot ourselves on the foot) - more generational power coming in - the rise of independent power-producers.
So there should be stability from a power generation perspective.
It's "long gone" because depending on which part of society you come from, you might have gone a few years without experiencing load-based power issues.
In general the power issues still exist once you step out of the suburbs or metros, but then again the DCs will likely be hosted there, or MS will enter into a power agreement that gives them preference over the rest of the average consumer.
I'm just glad that we'll have Azure DCs as a start, and hope Google and Amazon follow suit if MS succeeds.
