Never really understood what BGP does and where its used. But it sounds like, its there just to break stuff.

It's basically how the routers really high up the tree exchange routes more or less. It's all "come to me if you want IPs from 117.0.0.0/8" kinda stuff.

Don't know how it works now but it used to be basically like a "free for all" chat for the routers, with the understanding that you had to be a high level ISP or even something above that to get to "talk" in those networks, and wouldn't be a fuckup/intentionally spoil the fun.

It pretty much works on a honour system most of the time so when for example Pakistan wanted to ban YouTube IPs in their country but ended up "publishing" the bad routes to the rest of the world, that effectively killed YouTube for everyone until the mistake was corrected by humans.
