My big question is: what kind of failures do you usually see from your providers? Link down? Link up, but withdraw some routes? Link up, no route change, but blackholing partial or all traffic? Anything else?Two more failure modes: Link up, receiving all routes but provider stops propagating your announcement outward. Link up but unusably high packet loss to some or all destinations.

Thank you all for the reply! It seems to me that Cisco performance based routing and other commercial solutions can probably handle the potential problems. How about operators that deal with this on their own? Is there a standard detection and recovery procedure? How long does it usually take, with or without scripting? Thanks! -Simon
