From their FAQ:
There's several different reasons. First, some downtime isn't planned. If we have a hardware failure, a problem with the network, or a problem with our point-of-presence provider, the event is unexpected and we can't schedule it. It happens when it happens.
When downtime is scheduled, we try to perform the activity during business hours at our office in the Pacific time zone (in the United States). This way, as many team members as possible are available to help with issues that might arise and get the work done. We try to stagger the events at different times of day.
It's important to remember that Steam is a global service, so there are always users online. Our peak user load is around noon at our local time, and our lowest user count is around 2300 local time.
When we have planned downtime, it usually lasts only a few minutes. As such, we'll do it in the early morning or in the late afternoon (again, local time) trying to avoid the peak time of the day. If we have plans for extended downtime, we'll do what we can to schedule the time as late as possible in the evening--with the caveat that we still need staff available to do the work or to help with any problems that might occur.
