We would like to share the current progress on availability of DevTest Labs on Microsoft Azure Government Cloud (Fairfax). We are in the process of completing the engineering work for the same and you can expect to use DTL on Fairfax by next week.
Currently, if you try to access DevTest Labs on the Azure government portal, you will be able to view it; however the product is not functional as a few development tasks are in the process of getting completed.
We will send out an update on our blog as and when we have working bits for you to work with.
Thanks for your patience.
Azure DevTest Labs Team
