After eliminating 4 instances with no information, there were 34 occurrences. Some takeaways:<div class="">- 18 unique TLDs represented in the 34 occurrences</div><div class="">- A median of 3 occurrences per TLD (that's to say that nearly half of them had 1 to 3 occurrences, the other half 4 to 7 occurrences)</div><div class="">- A median of 22 days between the delegation and the report, with some very late reporting (maximum was 568 days)</div><div class="">- 7 brand/exclusive-use TLDs, 1 GeoTLD/Governmental registry among the 18 TLDs</div><div class="">- 23 cases reported as service disruption, 9 as networking errors</div><div class="">- 21 cases affected company networks, 7 a single local computer, 2 application development environments, 1 web application</div><div class="">- In 24 cases the registry was not contacted, in 5 the registry was put in contact with the reporter, in 1 registry stopped controlled interruption, in 1 no action was taken</div><div class="">- All 5 known outcomes that were reported were that the network was updated, all others are unknown</div><div class=""><br class=""></div><div class=""></co-chair></div><div class=""><br class=""></div><div class="">What was already known:</div><div class="">- No human-life threatening collisions</div><div class="">- Very low number of reported occurrences</div><div class=""><br class=""></div><div class="">What I expected and was confirmed:</div><div class="">- No IDN TLD collisions reported</div><div class="">- Brand TLDs having a share of the occurrences</div><div class="">- Little data on outcomes (people usually don't go back to tell their history after problem is fixed)</div><div class="">- Very few (1) instances where interruption was interrupted</div><div class=""><br class=""></div><div class="">What was unexpected to me:</div><div class="">- Very few (1) occurrences with GeoTLDs. It was forecasted that since many multi-site and global organisations built network hierarchies with city names and airport codes, those would have a higher incidence of collisions. Even some suspected cases like .cba, a brand, was supposed to generate collisions with geographic identifiers used in Chiba (JP), Córdoba (AR) and Cuiabá (BR). </div><div class="">- Late reporting. Considering most people wouldn't wait almost 2 years to troubleshoot a problem, that indicates that some other conditions had to change for the collision to occur: actual registration of a colliding domain, network reconfiguration that allowed it to happen etc. </div><div class="">- Reduced number of attempts to include registry into the incident response</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Rubens</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Sep 26, 2017, at 8:30 PM, Steve Chan <<a href="mailto:steve.chan@icann.org" class="">steve.chan@icann.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="WordSection1" style="page: WordSection1; font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class="">Dear WT4 Members,<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class="">If you’ll recall, WT4 requested additional information for reports of name collisions.
