Problem claiming MSDN product keys via VS Pro subscription

I'm getting the below error when trying to claim any product keys from my.visualstudio.com:

We are sorry, but our system has detected a problem with your account. If you are still getting this error message after 24 hours, please contact support with the date and time you started having this problem and with your subscription information. Message code: 715-123150.

I raised a ticket with support and got the below response:

As we improve our infrastructure and systems in alignment to the Secure Future Initiative (SFI) we have temporarily disabled the creation of new azure sponsorships and product key claims via Visual Studio. We are rapidly working to restore this functionality once the necessary upgrades are completed. Thank you for your understanding. This ticket will be closed.

Can anyone else with a VS Pro subscription claim product keys, or is this response accurate? The blog link they've included seems irrelevant to the issue.
