My random tales:
One night, playing bunch of Halo, I got an Xbox 360 voice message. “Message to all recent players. Fukushima nuclear power plant just exploded. You should stock up on iodine tablets.” (I almost sent back a message saying “thanks for your concern, but I’m in the Chernobyl fallout zone and I turned out just fine thank you”)
Pluto photographs from New Horizons? Frigging NASA retweet. (Edit: Actually I think it was a retweet of someone making a Disney meme about Pluto the Dog)
Most recently, I got a random Discord message from a British YouTuber I follow saying “the Queen just died, please be respectful and stuff”.
I was on a MUD (old multi-player internet text rpg) called Three Kingdoms when Princess Diana died. Over a hundred people online at the time from all over the world.
It was a huge shock for everyone, followed by a strange communal grieving for a well-known and liked international figure.
