Sorry, I think we're miscommunicating; I mean the non-running instances
here, which exist in S3. Not the running instance.

Ah, I guess I've been working at Twitter for too long. When we design we
-expect- the instance to go away. Except now, when we don't use instances
anymore and everything is on our own bare metal because we have serious
performance needs that cannot be met by Ec2 or any cloud hosting anymore.
This isn't to say that we don't farm out tasks to ec2 from time to time,
but we don't depend on it.

You should see Adrian Cockroft's reporting on EC2 and the variances
in performance in the same  zone. It's very interesting.

That would be interesting; I currently lead the security team here at
Twitter and prior to that lead the Operations team. I've keynoted various
operations conferences (notably, O'Reilly Velocity for a few years) and
have much to share on building very, very large systems (and the small ones
