I'm unable to create a VM in the West US region right now (will try another region soon). I keep getting this error (tried different network, no network, different storage etc.)
Allocation failed; unable to satisfy constraints in request. The requested new service deployment is bound to an Affinity Group, or it targets a Virtual Network, or there is an existing deployment under this hosted service. Any of these conditions constrains the new deployment to specific Azure resources. Please retry later or try reducing the VM size or number of role instances. Alternatively, if possible, remove the aforementioned constraints or try deploying to a different region
