We are currently up, but we have a white-list while we sort out the rollback.
The rollback from the host got rid of the chunk issues, but also various areas of the world has been… wiped from the universe, such as the entire spawn area.
We are currently in the process of uploading and rolling back from a backup made during the morning of the 2nd of March.
We really appreciate the understanding and patience while we sort this out.
