doug madory is asking me for a cite for the exciting 1997/8 128/9 bgp
event.  my memory as reported to doug is

    soon after the 7007 incident, an engineer in a UUNET lab, not
    realizing they were connected to the real internet, used the hidden
    bgp test command to generate 128/9 chopped into /24s.  took uunet
    down, but not before it propagated.

does anyone have a useful cite?
