We finished the original study. Since we have been getting some interesting
results and nobody has raised any issues, I'd like to continue it for the
time being. We will be limiting our announcements to 188.8.131.52/20 (and
its sub-prefixes, though generally only up to 184.108.40.206/23), though
other researchers may be using other parts of the /19.
Please feel free to contact me directly with any questions.

> Hi NANOG,
> From August 24 to October 4, the University of Washington and Georgia Tech
> will conduct an Internet routing study using AS-PATH poisoning. The study
> will *only* affect the Georgia Tech experimental prefix 220.127.116.11/19(and its sub-prefixes). The prefix serves *no active users/services* so the
> study should not affect any production prefixes or users. We plan to insert
> AS numbers into our announcements to route around some networks. We will
> always start AS-PATHs with our own ASN 47065. We will limit ourselves to at
> most 10 announcement changes per hour (and generally will change the
> announcement for a given sub-prefix at most every 90 minutes).
> This experiment is almost identical to one that Georgia Tech conducted in
> June and July without problems or complaints
> (http://mailman.nanog.org/pipermail/nanog/2011-June/037527.html), so we do
> not anticipate any issues. Others have done similar studies in the past
