I have three characters in three different servers. We've been trying to play for 3 days (!) and all we get is "World Full" (1017) on all three servers (Phoenix, Ultros and Ultima). Discount the posted maintenance times - we know better than trying to login while maintenance is going on.

When does Square Enix expect to resolve this issue?

That situation is unacceptable. Square Enix needs to understand no one is willing to pay a monthly subscription fee for a service that does not work!
