  • 11. New York-New YorkFriday, 8 February 13
  • 12. New York - Global Internet Hub • New York City (NYC) is a major Internet connectivity hub • Ashburn/Washington DC (ASH) is the other for US-Europe traffic Emile Aben, AIMS5 12Friday, 8 February 13
  • 13. Paths through NYC/ASH to ns.ripe.net Emile Aben, AIMS5 13Friday, 8 February 13
  • 14. 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 NYC Emile Aben, AIMS5 14Friday, 8 February 13

  • 18. RTT US -> AS24970 (DE) Emile Aben, AIMS5 18Friday, 8 February 13
  • 19. • Viz: Interactive maps / plots • What I want to get out of this: – ideas on what the best targets would be for individual RIPE Atlas probes (given limited probing budget) – compare notes to others who have Sandy data • Data: Same as other RIPE Atlas Data Emile Aben, AIMS5 19Friday, 8 February 13
