Anyone notice strange announcements for

The alerts we got were because our AS number was showing up somewhere
else in the world.  Whether it's "legit" IP space or not - it still
warrants investigation on a high priority from my perspective.

I have nothing against Randy or anyone else involved with this project
.. to be quite honest I'd be interesting in seeing/hearing the results
... but I believe a more careful approach is in order with consideration
for the folks effected.

This was a test using unassigned IP block, unless I'm reading it wrong.
If a noc alerted on this it should have still be a low priority issue.
I don't see any issues with the way this was carried out at all.

But isn't this method kind of related to how an network from the
Mediterranean/Mid-east went about blocking what they felt was
undesirable/offensive content from entering their network?

i think herein lies the rub.  it is not prefix hijacking and in no way
should it appear that way to you.  i suggest tuning your detectors.  i
am told that path poisoning is used (futilely, we hope to show) in day
to day ops by folk to try to avert dos attacks.
