The old SunOS 4.1.4 shell server, eskimo.com, is up.  It will be even slower than normal as I am writing backups.  That machine hasn’t been backed up since 2013 owing to the fact that any updates for SunOS have long since been discontinued so it is essentially static.  User data is stored on an entirely separate server that is backed up weekly.  None the less I like to back it up once in a while just to make sure there are no unreadable sectors on the disk and nothing has gotten badly corrupted.
