BGP is one of those things that make the internet fragile yet resilient at the same time.
Fragile in that any person who controls an Autonomous System can advertise routes and if your neighboring AS'es are not configured to filter out stuff it will just keep propagating. Imagine a government deciding to just reroute traffic to their data center maliciously. Obviously a good chunk of the internet will go WTF and blacklist the route but not before you get a deluge of data.
In the same way it is easy to route around traffic. Congestion in the midwest? No problem. Send the traffic down to Texas. All this is built on network admins trusting each other for the most part.

- feld 12y agoBGP route hijacking is not uncommon, and it's used to capture traffic of your victim without them knowing. BGPMon can tell you if this is happening to your AS http://www.bgpmon.net/ http://www.bgpmon.net/
