As shown below, the new SoftLayer Datacenter in Norway is not recognized by the API. This call works with other Datacenters.
SoftLayer.managers.hardware._get_location(package, "osl01")
Traceback (most recent call last):
...
SoftLayer.exceptions.SoftLayerError: Could not find valid location for: 'osl01'
I am not able to replicate this using Bare Metal (Package 200) as a test. Can you specify which package ID you are seeing this with?
