I noticed at http://uptime.netcraft.com/up/accuracy.html#whichos
it mentions that NetBSD doesn't provide uptime stats that Netcraft
can use to report how long a NetBSD host has been up.

Obviously, "uptime" at the shell reports this very information.

Is this info being blocked for some reason so that websites like Netcraft
can't determine NetBSD host uptimes?
