Emergencies can be planned ahead of time?

Perhaps they could have used "Critical Maintenance" instead...may have some weird translation issues though, who knows.

Either way it is unscheduled maintenance. For such instances it is not uncommon to refer to them as emergency. The wording may seem a bit strong, but it has a purpose. This is not something they wanted to hold off on any longer than they could. Once QA testing was complete they wanted to put it out there for us as soon as reasonably possible--and that meant scheduling it where it might impact the playerbase the least.

Imagine the $h!t -storm if they completed testing and took things down for 5 hours Saturday or Sunday during a more universal primetime. The time chosen was a compromise.
