I think this is not correct anymore:
http://net.t-labs.tu-berlin.de/~prichter/imc238-richterA.pdf

Nearly all customers at DE-CIX Frankfurt use the route servers.

I think many things happened in the past to make sure route servers run stable and reliable. With our proposal we are pushing hard in this direction. Especially, for large IXPs such as DE-CIX, AMS-IX, Linx or Netnod setting up bilateral peerings does not scale anymore (who wants to maintain 500+ BGP sessions?). Route servers are the only solution to keep the setup process manageable (from my point of view).

Best regards,
Thomas
