I don't work for Disney so it's not like I have inside info. I just remember seeing the same Indy refurb appear on the November calendar year after year. I always visit the parks sometime in November, so I tend to review the calendar for that month a lot. If Indy shows closed Nov 14-16 and open again Nov 17, then I would expect the listed closure dates to hold. They don't usually shorten already short refurb windows like that. Of course, if something unexpected/problematic happens during the closure, rides have been known to stay closed longer.
