&gt; A casual browse through the other entries seems to suggest that people mess up BGP announcements all the time.<p>While true, incorrect bgp announcements happen all the time, I think this is one of the cases that Hanlon&#x27;s Razor probably does not apply: most of the time they are not a result of people messing up - rather the bad announcements come from spammers&#x2F;malware spreaders needing new IP space because their current (likely hijacked) IP space has gotten blacklisted and is no longer effective.
