RPG Palace will be moving to a new host (hopefully) within the next two weeks. The process is intensive so there will be some slowdown. Before the host switch, the site will be shut down for database migration. After that migration and before the host switch, the site will be available but may be slower than normal.
Right now I'm not sure when the database migration will happen; it should be as close to the host switch as possible but right now I don't know exactly when that will happen.
