For those that don’t use Rackspace Cloud sites…here is more detail on the timeouts and why they happen:
http://www.rackspace.com/knowledge_center/article/connection-timed-out-error-message-1
“The bottom line is that data must be sent back to the client’s browser to keep the connection alive. So regardless of what sort of processing a page is doing, it must return data frequently or the load balancer will assume the connection has been dropped and will forcefully terminate it. Put simply, there will be some limitations of the shared architecture of Cloud Sites that will not allow us to resolve all issues for all customers.”
