Systems
Mirror
TODO. Syscom is currently working with CSCF to identify a plan for mirror.
Website
The CSC website is a static site, and will be straightforward to maintain during the outage.
All user and club sites are hosted in home directories (which are unavailable), so we will display an outage page (with a 503 status code).
Since the outage is for a week, we need to maintain email services during the outage. An initial plan by ztseguin and jxpryde:
- rsync users' .forward, .procmailrc and .maildir to a local directory on mail, allowing mail to continue as expected
However, this requires:
- Users not reference any scripts, programs, etc. in their procmailrc file that reference things in their homedirectoy
