Just a quick note now that our experiments have been underway for a month. Our study has been running smoothly so far, and we expect to eventually have an interesting report on it. If possible, can someone from Hurricane Electric please contact us off list? We have a quick question about our study. Thanks!

On behalf of the community, if I may be so bold (and I'm sure others will speak up if they disagree), thank you for the notice of this experiment. Also, thank you for doing the research. -- TTFN, patrick On Aug 18, 2011, at 19:32, Ethan Katz-Bassett <ethan () cs washington edu> wrote:Hi NANOG, From August 24 to October 4, the University of Washington and GeorgiaTechwill conduct an Internet routing study using AS-PATH poisoning. Thestudywill *only* affect the Georgia Tech experimental prefix 184.164.224.0/19(and its sub-prefixes). The prefix serves *no active users/services* so the study should not affect any production prefixes or users. We plan toinsertAS numbers into our announcements to route around some networks. We will always start AS-PATHs with our own ASN 47065. We will limit ourselves toatmost 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 wedonot anticipate any issues. Others have done similar studies in the past (e.g., Randy Bush et al.: http://www.psg.com/~olaf/measurements/as3130/visibility.pdf<http://www.google.com/url?sa=D&q=http://www.psg.com/~olaf/measurements/as3130/visibility.pdf). If, for any reason, you want us not to include your ASN in announcementsforour prefix, please opt-out at any time before August 24 at: http://www.surveymonkey.com/s/9P2TD7T . A few ASes opted out of the previous Georgia Tech study, and we will continue to honor thoseopt-outs.Please feel free to contact me directly with any questions.
