Hello,
Thank you for letting us know it is up again.
I will let Systems Management know.
Be aware it may happen again and retry periodically.

Hi,
Usually the catalog maintenance occurs on weekly Monday, the signature file .sha512.sign might not be working correctly, or there might be a need to troubleshoot on the server that you are using DSU on, collecting the report and analyze by the support. A support case needed to be raised if the issue persist on the server. Suggest retry periodically mentioned by Charles.
Alternatively, after checking the DSU troubleshooting guide, probably you can use --ignore-signature to skip the signature verification.
