I remember reading that OVH is very popular in the Scene[0], for running topsites and the like. The reliability and bandwidth must be pretty good for them to be used by the Scene.
My bad, maybe I got the popular seedbox hosts confused with the popular topsite hosts. For some reason, I seem to remember OVH being mentioned in a scene notice. It might've been when they busted a topsite for leaking releases to a seedbox used by a private torrent site uploader.
Yep, if OVH were referred to it would only have been in a negative context, e.g. outing a P2L (Pay to Leech) site or someone seeding files to torrent trackers.
