Had all 3 of my clients disconnect simultaneously so I am assuming it was a zone crash. I had just kill Emp and Blood of Chottal during which I had guarded my bot, walked out to kill the door guards remembering that I needed to call my bot over. Did a #bot group order follow and boom.

*edit* After I came back, all my guildies (in different zones) reported they crashed too, but when I did a "/who all" there was still too many people on to list them all so it was serverwide, but not. Funky.
