I love how people run around their house checking to make sure the internet is working before they even try to check the POL website...
I like how people rush to point out things that don't say *** about maintenance. Still says 'Server Status: Up' if you'd bothered to look for yourself. It's not on the main page, not even on a page you get to with one click. It can't be found without without digging into the forums or five days back on the news feed in unrelated and unlinked posts to see anything about the maintenance at all.
So yeah, you feeling 'smart' for knowing to check the normal channels for this stuff is a bit of a derp when it can be pointed out that none of them are helpful.
SE pulled ninja maintenance because they didn't wanna hear people whine about it being ten hours long. Whatever. Not finding any front-page info about it is a logical and valid gripe though.
