Linode 11th most popular host: VentureBeat
Saw the link tweeted by Oles from OVH, was pleased to see Linode come 11th in the list of the most popular hosts for the top 100k websites on the net.
I don't think cloudflare should be in that list, it's not a hosting company in any normal sense.
It's actually quite interesting to see how many of the top 100,000 most visited sites use Cloudflare protection, though, so I'm glad they left it on the graph.
Cloudflare appears on the list because it's impossible for HostCabi to know which actual provider hosts Cloudflare protected sites. Once someone puts their site on Cloudflare, there's no way to know what their IP/provider/etc is. That's the point of it.
Impossible? Impossible is a challenge

Oh dear, however will I find who is behind that?

You can get rid of the direct link but most people don't. Also asking netcraft tends to work.
