SixtyGig, as I know it at least, has been shut down. You can now access the entire server, all the maps, all the plugins right here:
Stacy is working overtime to bring back the server though, so don't fret, SixtyGig isn't dead yet!
But I do have one more promotion to hand out before I retire; For the first time in over 4 years of SixtyGig's life span, I am promoting a veteran . . . to admin!
I'll still be floating around on the forums, I'm not going anywhere, so this isn't goodbye. But, it is good luck!
Have fun everyone. I had a great ride, made many lifelong friends, and am proud to have had the honor to run what I consider one of the best, most mature Minecraft servers ever created.
