Attestation signing output?

Is it just me or is Attestation signing not giving any comment or
information about why the process failed just now? I tried different
browsers to same effect.

I can only see it failed in Preparation phase, which is too early.

    Of course... something broke our automated process and the CAB file was not signed.
    I also notice we need to have separate CAB files for x86 and x64 now :)

    Where did you see that you need separate CAB files for x86 and x64? I combine all architectures into one INF, so such a requirement would be astoundingly counterproductive. You've always been able to sign multiple packages by making them subfolders of the top level in the CAB.
