[ih] Large scale BGP failure in early 90's

[Craig Partridge]

Wasn't that the same pattern that took down the AT&T network c. 1990 (a
busted update that was propagated before being fully processed)?

I seem to recall Dave Mills actually triggered a similar issue in the early
Internet (I do recall he talked about some bug in his code and that some
authority figure, Vint?, was mad at him at the time).
