Cogent was advertising their routes elsewhere. It was the customers of Level3 that got really screwed, cause when their replies to Cogent IPs ended up on Level3's network, the packets were simply dropped (making the connection look dead). At one point, Level3 was proxying the web requests to a website saying that Cogent was the cause (which wasn't the truth). Level3 quickly removed that proxy when enough people called Level3 and complained (I know someone who called and complained).
No, that's just wrong. Cogent does not have full transit. They buy selected transit from Verio for ISPs that they've lost the game of chicken with (think AOL). They didn't buy transit via Verio to Level3, so Level3 never saw their routes.
