Connection Issues. Is there any official word, at all?

[Mitisuki]

Since 3.3 has launched, I've had many, many issues where I'll lag for 20-30s a fight, this'll occur an entire duty, and then I get a 90006 error. Tonight it has persisted since the first boss of World of Darkness, and I've been locked out of every boss fight but the first because I cannot maintain a stable connection. (Thanks to the group very much for not kicking me, I wanted that farthng.)

I've run internet speed tests while these happen, and get between 1-12ms ping, 119-128mbpgs download, and 9-13 mbpgs upload. I've played World of Warcraft, The Old Republic, World of Warships, and Overwatch without problem, for several hours, specifically to see if it is on my end. I've gone through my virus scanner and firewall to see if maybe something was being blocked. I've flat out disabled both just to make sure I haven't overlooked anything. I have a direct connection to my modem, there is no wifi.

I've played FFXIV for two months in 1.0, and since ARR launch. Excluding expansions and major patches, a week or so out included, I have never had these kind of issues. Since 3.3 has launched, it happens almost daily. Is there any information on this that I've missed, at all?
