Fov120.com is down, which also includes all of Aardappel's engine sites and the master servers... so currently, Cube is FUBARed. In the meantime, anyone wanting to post server addresses or information relevant to the outage can reply to this thread. Quadropolis isn't directly associated with Aardappel's sites, so we don't have any more details on the outage than you do.
Sorry about our sluggish reaction - I've been busy for Easter weekend.
Edit: Never mind this post, it's back now. Hallelujah!
