linux.dell.com seems knackered

Yesterday, we went from "connection refused", to all resources for which I know links yielding "403 forbidden".  An example would be the installation instructions for installing the iSM, supposing to be at https://linux.dell.com/repo/hardware/ism/ , plus not being able to get the bootstrap.cgi setup script, plus not being able to sudo dnf makecache . It throws the error

Errors during downloading metadata for repository 'dell-ism-update':
  - Status code: 403 for https://linux.dell.com/repo/hardware/ism/os_dependent/redhat/RHEL8_64/repodata/repomd.xml (IP: 143.166.156.113)
Error: Failed to download metadata for repo 'dell-ism-update': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Just sayin', we Linux shops are having a slightly rough time, and would appreciate some repair of these backends.
