and

> it was not a peak time

So, doing maintenance on US servers, on a Friday, during a timeframe when the US is getting off work is not a peak period of time for those servers? That sounds a bit like using numbers to lie, or at least minimalize the impact.

I can see how it might have been a lull when considering all Heroku instances (since most of Europe is headed off to bed), but I have the feeling this was not the case for the US servers. I could certainly be wrong, since I'm just speculating, but it just seems fishy.
