Get a shift on, why aren't you on here?

One can only wonder...

But, more on the serious side, I only think Linode has a few hundred physical servers (ie. the host servers) at the most at any given time (taking into account that server hardware is constantly being replaced and retired).

OVH is actually at 140k now, and they just built a new datacenter here in Montreal with a max capacity of 360k servers. They seem to use some strange custom form factor that's halfway between rackmount and blade.

Linode has 16,000 CPUs, according to their stats page, and unless things have changed, 8 cores per host. This would indicate that Linode has 2000 servers.
