I just received this email on November 2nd at 6pm.  I hadn’t heard a word of this prior.  Thanks for the warning…

Windows Azure CTP participant,

You are receiving this mail because you have an application or storage account in Windows Azure in the “USA - Northwest” region.  Windows Azure production applications and storage will no longer be supported in the ‘USA-Northwest’ region.  We will be deleting all Windows Azure applications and storage accounts in the “USA - Northwest” region on November 3rd.

To move your application/storage, first delete the project using the “Delete Service” button.  Then recreate it, choosing the “USA - Southwest” region.  (It may take a few minutes for your previous application and storage account names to become available again.)

Note that deleting your storage account will destroy all of the data stored in that account.  Copy any data you wish to preserve first.

If you would like help migrating your project or have any other concerns, please reply to this mail.

- The Windows Azure Team
