Same problem over here. 90k errors started Friday evening. It seems to be a bit better today because after logging in it now takes between 15-30 minutes rather only 2 like yesterday before the server connection breaks.
Still, in this state it makes simply no sense to enter a dungeon or start any long running task.

Data center: Chaos (well, that name fits quite well)
Game world: Zodiark

Location: EU, Germany
ISP: German Telekom

If it's a server issue and not Internet backbone issue I guess the prolonged silence from SE implies that they are planning to sit it out until the scheduled maintenance next week.
