The word "Shutdown" has been lingering in my mind for the past few days. Been seeing a lot of coincidences with this one.
Not only did the first post mentioning a shutdown happen on this day last year, it shows up on the clock for today as you pointed out. The next post containing the word "shutdown" was post 365, possibly signalling the one year mark?
Something else I noticed, yesterday, regarding a Blue Check Mark account. The DEFCON Alert tweeted something about North Korea and a nuke site. Of the three other posts containing the word "shutdown", all of them either mention NK, nukes, DEFCON, or all of the above.
