[ NNSquad ] Re: Peering dispute cuts off Sprint<->Cogent Internet traffic

There's no violation of any RFCs here, it's a peering dispute which is quite
common on the Internet.

It's a long running myth that routes are automatically rerouted on the
Internet.  Unless one of the two end-points is dual-homed with 2 completely
separate ISPs configured for BGP (or DNS remapping), any break in the route
means a disconnection between the two points.  Even when BGP does exist, it
takes some time for the routes to propagate so there's always some outage
for a period of time when there's a break in the link.

OK, so what has happened to the "treats censorship as damage and routes 
around it" Internet?  Even if Embarq and Cogent are no longer talking to 
each other, the routers should be automatically finding routes via other 
carriers and sending the packets -- around Robin Hood's barn if 
necessary, but the Internet is supposed to be _robust_.  Jon Postel 
designed it that way -- I've read the RFCs.  That's what ARPA specified 
when they paid for the development of first the ARPANet and later the 
Internet -- and what NSF paid for when they branched off NSFNet and 
allowed commercial traffic.

Are these guys programming their routers to just drop packets with 
certain destination IP addresses, instead of finding the shortest 
available route?

I'm beginning to think that Congress (or perhaps an international body 
similar to the WTO) should make the core RFCs (IP, TCP, BGP, FTP, HTTP, 
SMTP, and RFC 822) have the force of law.  And anybody who violates 
those protocols should be fined and/or have their connections turned off.
