  1. 1. Hurricane Sandy, asseen by RIPE Atlasemile.aben@ripe.netNANOG 57
  2. 2. RIPE Atlas• Measuring the Internet – For the community – By the community• https://atlas.ripe.net/• https://labs.ripe.net/atlasEmile Aben, NANOG 57 2
  3. 3. 2500+ Hardware Probes Deployed 104 countries 1202 v4 ASes (2.8%) 402 v6 ASes (6.1%)Emile Aben, NANOG 57 3
  4. 4. Measurements• Ping(4/6)• Traceroute(4/6)• (DNS/HTTP/SSL)• Towards “fixed” destinations: – DNS root servers + RIPE Atlas infrastructure• User Defined MeasurementsEmile Aben, NANOG 57 4
  5. 5. What Do We Want From You?• Use RIPE Atlas!• Feedback on how to make it (even) better• Today’s presentation: How RIPE Atlas saw Hurricane Sandy – https://labs.ripe.net/sandy-2012Emile Aben, NANOG 57 5

  13. 13. New York-New York
  14. 14. Paths through NYC/ASH to ns.ripe.netEmile Aben, NANOG 57 14
  15. 15. Compare pre/post Sandy Paths dst: ns.ripe.net / AS3333 / NL pre: 22:00 UTC vs. post: 09:00 UTC Destination Path moved away from NYC Path kept going through NYC Path started going through NYC Path not through NYCEmile Aben, NANOG 57 15
  16. 16. Compare pre/post Sandy paths dst: d-root / AS27 / MD,US pre: 22:00 UTC vs. post: 09:00 UTCEmile Aben, NANOG 57 16
  17. 17. Conclusion• For the paths that we measured: – Paths were noticeably more unstable on 2012-10-30 (UTC) – Paths moved away from NYC, but not completely• There will be a next time (the Mayas were wrong) – Next time: ???• How can RIPE Atlas serve you best?Emile Aben, NANOG 57 17
