I'm not sure whether this is just for my account or a general issue, but the new link to download the vSphere Supervisor Services from the Broadcom Support portal does not work for me.
The following link does not list any items for download:
https://support.broadcom.com/group/ecx/productdownloads?subfamily=vSphere%20Supervisor%20Services
This is the correct link for me:
https://support.broadcom.com/group/ecx/productdownloads?subfamily=vSphere%20Supervisor%20Services&freeDownloads=true
