On a related note, if you want to really see server instability try playing on Thaurissan primte time. The server crashes almost on a daily basis. We suspect that there is a honor update that occurs during our prime time causing the problems.

Go to the Oceanic server page during Aus prime time, all you see is FULL, FULL, FULL, HIGH, FULL, FULL, HIGH... I can screenshot it for you if you think I am exaggerating.

Sometime during the evening the server will start lagging, you will get a few minutes of trying to loot and nothing happening. Eventually you will be disconnected. Connecting again will be ok for a few minutes and then it starts again. If you force quit (alt+F4), then you can't log in as you get a "Character already exists" message. I've had "Instance not found" errors trying to zone into instances.

During the holidays it seemed to work fine but now everyone is back to the daily schedule the server just seems unable to handle the load. The game becomes unplayable for at least an hour 3-4 nights a week excluding Tuesday night shutdowns which also happens prime time on Oceanic servers and I have yet to see any compensation for these instabilities.
