Battle.net Page said:We will be performing a Diablo II ladder reset on June 17 beginning at approximately 9:00 a.m. PDT.
The reset is anticipated to require approximately six hours of downtime to complete,
and during that time all Diablo II Battle.net realms will be unavailable for play.
When the reset occurs all existing ladder characters will be moved to non-ladder.
This provides a fresh start and new competition for leveling supremacy on the ladder realm.

So anyone want to start on the fresh Ladder with me?
