DESCRIPTION:Abstract:\nOver the past decade\, Internet eXchange Points (IX
 Ps) have been playing a key role in enabling interdomain connectivity by p
 roviding a shared fabric where Autonomous Systems (ASes) typically peer. W
 hile the relevance of IXPs is undeniable\, their contribution to the shapi
 ng of the current Internet is not fully understood yet. Using historical I
 XP membership and traceroute data (2008-2016)\, we show that the impact of
  IXPs on path-length is limited. Surprisingly\, Internet path-lengths have
  globally barely decreased over the last decade\, regardless of whether th
 ey cross IXPs or not. Instead of a “path-shortening”\, we observe a di
 version of the routes away from the central Tier-1 ASes\, supported by IXP
 s. This diversion has however not fundamentally changed the existence of a
  hierarchy\, but rather replaced the central Tier-1s with a new set of pla
 yers.\n\nBio:\nIgnacio Castro is a postdoctoral research associate at Quee
 n Mary University of London  where he holds an EPSRC grant (researcher Co-
 I for the £2.4M EARL project). He obtained his PhD while researching at t
 he Institute IMDEA Networks (Dr. Sergey Gorinsky)\, and visiting the Inter
 national Computer Science Institute at Berkeley (Prof. Scott Shenker). His
   research combines networked systems and economics with an special focus 
 on interdomain network interconnections and the macroscopic evolution of t
 he Internet (e.g.\, IEEE/ACM ToN\, IEEE JSAC\, WWW\,  ACM CoNEXT). He is a
 lso actively involved in conference organization (e.g.\, ACM IMC treasurer
  and social chair\, ACM SIGCOMM Publicity chair) and obtaining and managin
 g large research grants (e.g.\, EPSRC\, H2020).
