How to roll back a Windows Azure Cloud Service deployment

As title really, I can't see how you can Roll Back an update to a Windows Azure service/site? Each "update" has a title, so I'd thought you could see a list of these updates, but I just can't see it listed anywhere?

I use https://manage.windowsazure.com, and these are cloud services.

There is no stack maintained of your previous deployments, if however your present deployment somehow fails than the fabric may use your previous deployment(It tries to initialize previous states). Your roles are just VHD(Virtual hard disk) with a copy of OS and your installation files running virtually, whenever you update, a new VHD is allotted and the previous is destroyed(if update was successful). Thus there is no way to get the previous deployments(its destroyed). You should store your previous builds locally or on a foundation server just in case you need it like you now.

Details on Rollbacks can be found here: http://msdn.microsoft.com/en-gb/library/windowsazure/hh472157.aspx#RollbackofanUpdate

To quote:

Windows Azure provides flexibility in managing services during an update by letting you initiate additional operations on a service, after the initial update request is accepted by the Windows Azure Fabric Controller. A rollback can only be performed when an update (configuration change) or upgrade is in the in progress state on the deployment. An update or upgrade is considered to be in-progress as long as there is at least one instance of the service which has not yet been updated to the new version. To test whether a rollback is allowed, check the value of the RollbackAllowed flag, returned by Get Deployment and Get Hosted Service Properties operations, is set to true.

Note It only makes sense to call Rollback on an in-place update or upgrade because VIP swap upgrades involve replacing one entire running instance of your service with another. For more information about swapping VIPs, see How to Deploy a Service Upgrade to Production by Swapping VIPs in Windows Azure.
