Indiana Jones Refurb April 2015

Does anyone know the dates that Indiana Jones in Disneyland will be closed for refurbishments? I am getting conflicting dates of 21/4 to 22/4 on touring plans but disneyland site so far has 21/4 - 25/4 and could be more. I am in Disneyland from 21/4 - 1/5 and hoping it is open at some stage. I am traveling from Australia.

April 20-May 1 are the refurb dates I have seen. It desperately needs the closure, too many times going offline these days.
