Internet traffic for Google, Facebook, Apple was briefly rerouted to Russia

In 1998, a hacker collective known as the L0pht testified in Congress that they could take down the Internet in 30 minutes.

It is believed BGP black holes could be one way of achieving this.

Basically tell every node "I've got the lowest routing cost to every node, send me all your traffic", and then drop all the traffic.

This is much better nowadays but bgp is still problematic.

It's not really better today. Possibly even worse.

In 1998 there were fewer than 5000 different networks (Autonomous systems) on the Internet. Today that number is over 80K. Network operators used to personally know each other and their clients.

So the automatic filtering is better today than it was in 1998, but it can still be easily bypassed.

I know for a fact that even as a tiny network, all you need to do to get the some of the biggest networks in the world to accept your (real or fake) BGP announcement is to email their support center.

Aren't ASNs capped at 2^15 (65k and change)? Or has the IPv6 expansion already started happening?

ASN's switched over to 32 bits around 2007
