I live in Australia. One day I received a very excited phonecall at a ludicrously early time from a Canadian Mathematician I knew (John McKay, Concordia. He's dead now but had been a figure in my childhood from his time in Edinburgh in the 60s. he had worked with John Conway early in both their careers) telling me this was rumoured to be coming, and asking me to get the word out and find out what I could. I pointed out I wasn't a mathematician or very well connected, he said "doesn't matter: Get to your national broadcaster and ask them to verify the story"

So I rang the ABC and asked to speak to the Science Desk. This was at around 7am by this time. I was connected immediately to Robyn Williams, the premier science communicator at the ABC, despite having no name, no evident back story or trust. He was absolutely delightful to talk to, agreed with a laugh that he often got excited calls about people squaring the circle or finding repeat patterns in PI digits and was used to crank callers, listened to me, probably did some checks and then said he'd contact somebody at Cambridge and see what the gen was. My memory is he called me back a little while later saying they'd confirmed a room was booked for a significant public announcement seminar, and thanked me for the tip. This was a long time ago, it's equally likely I misremembered and he gave me a name to check with in the UK and I did the leg work. The point is, I wasn't just told to bugger off.

Nowadays it would be all over twitter. John was a bit old school and liked phone calls. They had internet emails in 92 of course I think he just liked the physicality of a call.
