All Mochi source code repositories have been migrated to github.com at https://github.com/mochi-hpc/ as of March 22, 2021.
If you are already using spack to install Mochi components, please update your Mochi repository at your earliest convenience:
spack repo rm mochi git clone https://github.com/mochi-hpc/mochi-spack-packages.git spack repo add mochi-spack-packages
The package names have not changed; this will just enable you to retrieve new versions as they are released by updating your cloned copy of the mochi-spack-packages repo.
