The only ride I can think of that is closed at Cedar Point (not a roller coaster, though) is MaxAir, which is similar to Kings Island's Delirium...at Kings Island, the only ride that is down (again, not a roller coaster) occasionally is The Crypt, but I guess it's gotten more reliable over the past couple of weeks...
They are the same just height are different between maXair and Delirium.
