General MSB announcements
We might as well have a sticky here for site-wide stuff that probably don't interest most people.
The first item: Users reported they weren't receiving e-mails. This was verified, and as of now we upgraded to postfix over sendmail. I tested just now and it works, but if it doesn't please let me know.
... Second post! Already!
So when I uninstalled sendmail since we no longer needed it, it didn't clean up after itself... but left a little present behind in /etc/network/interfaces.d/ , which was causing ifup -v eth0 to fail. In a layman's terms, the machine hosting MSB was up after that but it had no functional network until I fired up a console (thanks Linode for that) and figured out wtf had just happened.
Sorry about the disruption.
