As a former ISP employee I occasionally like dipping my toes into some networking stuff, and this 25-minute video from The Serial Port is a good retelling of the day in 2014 when one of internet’s important routing tables crossed a threshold of 512K, which caused all sorts of trouble:

What I appreciate about The Serial Port is that they always seem to actually test the vintage hardware or rebuild the old software they’re commenting on, and this time was no exception: they grabbed a classic unsung hero of ISPs, a Cisco Catalyst 6500-series router, and then recreated “The 512K Day” in their studio.

This was a nice comment under the video:

Have absolutely no knowledge about networking, but watched this video as if a thriller movie. Thanks for opening my world of tech to networking.

Yeah, the video is kind of nerdy and intense, but maybe you’ll enjoy it; even a classic aging piece of hardware with an arbitrary ticking-bomb limit deserves some respect.

Also, the funniest comment:

I had a 2.4k day a couple days ago when I realized Farm Sim 22 only allows a max of 2400 bales. Couldn’t load into my saved game. Had to go into items.xml and temp remove a hundred bales.
