ALL Characters. Doesn't matter what Datacenter or Character I'm logged into. I've got same issue on characters on Oceanic, Crystal, Dynamis and Primal.
Usually after I've been logged into game for a few minute at least - I'll be doing something like crafting and BOOM I'm disconnected. Or just parked in Free Company house moving materials around my character.
I've been dropped multiple times Sunday, Monday and now Tuesday. If fact I was just dropped a 2nd time just now with 90006 error crafting a stack of 99 items (TWICE in a row dropped trying to do that) as I type this.
ISP: Spectrum - Missouri
Region: Midwest - Missouri
Rebooted Cable Modem, Rebooted Router, Rebooted Computer (In that order) - did Speed Test and validated functional.

NOTE: I had ZERO problems on Saturday like this, but since Sunday it's been non-stop issues. I suspect DDoS attack is still active as the drops are too often and lag in game is also becoming unplayable. I left early last night as I got tried of being booted out of the game. Nothing has changed on my computer since Saturday.
