The rendition I heard assigned the moniker because one of the major news
outlets said that the mistake which triggered it was "like a misplaced
ampersand". It was certainly the one on the wall beside his legacy Chevy's
sombrero.

My oh my, how the versions differ.

As was recounted to me, the outage was about 19 hours, and was due to
the semantics of Cisco config mode. Something like:

router ospf 1234
redistribute bgp subnets route-map blah

(everything fine, now let's turn it off...)

no redistribute bgp subnets route-map blah

So tell me, does this turn off the redistribution, or just remove the
route-map... :)

And this is certainly worth remembering. Had I not known of this, I
could likely have made the same mistake at some point.
