[swinog] Dark fiber Lausanne information request

Hello,

My company is currently looking at the possibility of moving our server infrastructure from the in-house server room to a datacenter in the Lausanne/Geneva area.

This would require us to be able to obtain a dark fiber or similar low protocol overhead/low latency network link. The link would be between our offices (Malley Lumières) and a datacenter (Brainserv or Infomaniak Satigny). We have started looking around and are having a few difficulties finding information on these matters.

Has anybody had experiences with the implementation of such a setup ? We are looking for feedback regarding pricing, complexity of implementation, possible more interesting options and co.

Thank you in advance for your help,

Antoine
