Difficulty to login is a foregone conclusion here from the flood of complaints on the forums so far, so no need to go there and let the good ol'community rage on the other threads. Though i would like to point out a few issues here, especially after the Maintenance took place:

1. A more frequent error been popping up "5006". Not sure what that is about, but it sure been happening a lot now during the god awful click-grinding process to steal a gap through that "1017" error we all know and love right about now.

2. Server listing been rather more glitchy post maintenance than it used to.

3. Noticed on the Connection Status on the character selection Menu. Before the maintenance, it was almost definitely on "Excellent" status give or take 10% of the time getting the "Good" status. However, after the maintenance, rarely get "Excellent" anymore and it usually set to "Good", and that usually goes hand in hand with getting the server listing up. When it's "Excellent" you get the listing, "Good" you are out of luck. (Checked with ISP and no changes done from their end regarding routings)

In case it makes any difference to pin-point the problem, the intended Server is in the Japanese Region being accessed from the European region.

Well, that's about it, though i am sure there are lots more out there, and would be great to point them out with the conditions they popped up to help narrow down the cause.

Good luck hammering that Start button!
