Thank you. You've provided a clean, concise counter to Lorenzo's original

showing that ios won't crash is very difficult because the number

Alternatively, why can't the test be conducted in a lab, with
interested operators providing router configurations and xOS versions to give
the test bed the most realistic sample of the 'net, without using the
Has anyone considered that the project may have indeed done testing of
available IOS/$ROUTER versions in a lab environment before even
considering testing on the 'live' internet? Reading the cited material
might be of benefit to the vocal complainers.
I think Lorenzo would be the first to admit that the timing of operator
notifications, and more importantly the wording, may be less than desired,
however this does not detract from the caution, and professionalism
exhibited thus far in this set of experiments.
This may be a well-run, very small experiment, but it's experimenting with a
space that's rarely explored and therefore less likely to have encountered
the same level of operational testing that horrifying garbage leaks have
Part of the problem is that because it is, as you put it, a rarely
explored problem space, the number of interested parties with sufficient
and varied resources is extremely small, resulting in a less-than-complete
Another part of the problem is that you cannot put the concept back in the
box. The black-hats do read operational lists, and with all the fuss
being made over possible breakage caused by AS-sets, some of them will do
will perform their own, possibly destructive experiments in order to find
out what specific $ROUTER versions do under various inputs.
So, which would you prefer.. Lorenzo at a known contact number with known
working hours (+31 20 535 4444, 10am to 5pm GMT +1), and with the
Internet's best interests at heart, or some malcontent with unknown
contacts, unknown hours, and very definitely not your best interests at
Unfortunately, option 3, do nothing to see whether it is actually
a problem, is no longer valid.
