Maintenance Again

There is a maintenece again today. Anyone know how much longer it will last?

What do you mean there's a maintenance "again" today? There is always maintenance on Tuesday nights.

And as usual, it is estimated at 3 hours, though there is always a chance it will end up being extended.

^This.

To my knowledge, all (most?) of Nexon's games go down for a weekly [scheduled] maintenance on Tuesday at 10pm Pacific for 2-4 hours (unless it's a special patch or update, then it's more). It doesn't matter if any of them had a maintenance a few days before or not.
