The first sentence:
At the following time, we will be performing emergency maintenance on Japan Data Center Worlds to restart servers as a temporary countermeasure against server congestion and to fix the data of characters unable to log in due to the 90000 error. During this period, the Worlds listed below will be unavailable.

Wha... Does this problem only exist and is acknowledged in Japan? And why are the [NA] and [EU] tags ONLY contain messages about the JP servers? Like WTH? Post JP messages by the JP reps in the JP forums and post information regarding NA by the NA reps with the [NA] tags, inferring that the message refers to [NA] servers. No, not English, when the tags say [NA] or [EU] they are talking about servers, not languages.
