I wish they could do this in the morning like every other online company in the world.
Instead of, you know....right after the majority gets home from work/school.
I agree. It's really annoying to get home after work, or just after finishing dinner and finding out Steam is down.
I'm nearly positive that valve took their data and extrapolated the time that the least amount of people are using the steam services and made their maintenance coincide with that. Yes, annoying for some, but it could be worse.
