But there is a difference between Fry's closing at some point, which anyone that has been into a Fry's in the past few years expects, and a surprise shutdown between Tuesday and Wednesday with no prior announcement (which is what was implied by the linked tweet and was the most noteworthy).

I think that the fact that we all did expect them to close at some point caused us to overlook the rarity of a company ceasing operations overnight and we just took some rando's word for it.

Edit: it seems like this unnamed source was correct. Closure information is now posted at frys.com, which isn't quite midnight but close enough. I'm still a little disappointed at HN in general for basically taking one unconfirmed source at it's word without any of the top voted comments questioning or asking for confirmation.
