How could you not have known? I mean just because you were out of town, couldn't you check your phone on the official site under "Special News"? It's the first thing that shows up on mobile? There is no way of you knowing if you don't check the website. I mean it's common knowledge that maint is normally before reset. And that if there IS going to be maint it's up in the "Special News" category a few days before maint actually happens....
