Not yet.  I try pretty hard to make sure the problem isn't me because it
usually is! :)

Oh, you know, "so many 9s or its prorated!".  So, not a lot of teeth
there.

Hrm... Linode used to advertise how many of each type of VPS was on a
machine.  Can't find that anymore, so I can't much speak for density.

I did however just stumble across somebody mentioning slowness on my
host in the IRC logs for Saturday (which would be around when I first
noticed it as well), so it may not be just me.  In which case, it's
definitely support-pesterin' time.

Thanks!
