World classification - server status

[MistakeNot]

Hi there,

Is there any planned maintenance or just update to statuses on world classification for European / global servers list -- in near future?

SE isn't going to tell us in advance when status changes will happen - and most likely can't tell us much in advance.
The status (congested, preferred, etc) of worlds change depending on how the population on the worlds change, not on any timed schedule. So it can be hard to impossible to predict when the populations have changed enough.
When status changes are made, it is always in conjunction with a maintenance - so it will not happen any earlier than next maintenance.
