Guess I need to find my copy/paste thread with the notices about the patch 2.16 stability problems investigation so everyone in here may be brought up to speed again...

Since March 5th, SE has been actively investigating stability issues. IIRC, tonight's maintenance is their third attempt in the last week or so to address them. Notices are going up in the Lodestone and the Status/Maintenance forums. You should also see them in the launcher, as well as a pop-up message when you go to launch the game after logging in. In case they've been missed, here's a link to the original post with the request to post details of your issues in the bug reports section:
