The difference between us and aviation is that fundamental flaws or mistakes that impact safety are required to be fixed and checked if you want to keep operating in the industry. We don't have that, so...
... so once again, route optimisers were at the heart of another serious route leaking incident. BGP is designed to prevent loops from happening, and has tools like no-export to help prevent inadvertent leaks. When people build "BGP optimisers" which reinject a prefix into a routing mesh with the entire as-path stripped and then they refuse to apply the basic minimum of common sense by refusing point blank to tag prefixes with no-export, it's a matter of certainty that leaks are going to happen, and that when they do, they'll cause damage. It's about as responsible as shipping a shotgun with the safety disabled and then handing it to a newbie. After all, the safety makes it more difficult to operate and if the newbie shoots themselves, it was their fault. And if they shot someone else, they shouldn't have got in the way, right? Nick
