In essence - yes, but most providers that provide connectivity (transit etc) - have best practices that include filtering route announcements for sanity checks, to make sure stuff like this just doesn't happen. I mean, even if a big dumb 3rd world telco (like these guys, or like some of our own homegrown ISPs) screw up router announcements, these are caught and filtered out so that this damage doesn't occur Unfortunately - PCCW (big hong kong ISP - pacific century cyberworks) that provides connectivity to lots of smaller asian ISPs - doesn't do this. And youtube suffered as a result. What pccw did to stop this happening was even dumber, they cut off all of Pakistan telecom for a few hours.
