We've been informed by the site admin that ftp.mcs.anl.gov is taken down due to 'cyber incident' - there is no ETA on when it will be back.
We've been using it the primary host for distributing petsc tarballs and hosting some externalpackage tarballs - so some of the petsc buils with '--download-package' option are failing. Obtaining petsc [and some most externalpackages] via git should work. I will update when ftp.mcs.anl.gov is brought back up. Satish
