Cyrus on Amazon EC2 and EBS?

[Zachariah Mully]

Howdy all-
	Is anyone out there running Cyrus on an Amazon EC2 instance with EBS? 
During these brutal storms we've had in the DC area, we've been 
discussing how to improve the resiliency of our operations and getting 
our mail systems out of our CO and into a datacenter is high on the 
list. I'm looking for any feedback on using Cyrus with Amazon or any 
other 'cloud' service (I'm also looking at Rackspace's cloudserver 
offering as we're already a customer). Any gotchas, performance, 
reliability issues, etc? About 120 users, 300+GB mailstore.

Thanks,
Z
