Same here.. got a notice this morning and while it's false, I still have
no response from Randy neither on this matter...

If they are going to involve our AS numbers and trigger alarms it would
be nice to notify us first... especially on something as major as a
prefix hijacking (potentially)

  randy lied but
  no packets died
  enough now

  More seriously, this is indeed reachability research. Try
emailing
the AS 3130 contacts although I'd imagine Randy will see this.

173.0.0.0/16 and 174.128.0.0/16 explains what is going on.
