Campus Network and CS Server Downtime, Thu, January 30, 2014, 04:00-08:00

Who is affected:
All users of the CS Department or campus network or computing infrastructure, including, but not limited to, e-mail, web service, and public login hosts.

What is happening:
During this window, OIT will be performing maintenance on the campus network, resulting in no network service outside the CS network. This outage will include internet service and wireless service all over campus.

Also during this time, the CS linux servers will be patched and rebooted. The penguins (tux, opus) and cycles (soak, wash, rinse, and spin) hosts will be reinstalled.

SPECIAL NOTE: As we are reinstalling the penguins and cycles login servers, all crontabs will be deleted. You will need to back up your crontabs before the downtime, and put them back after.

Why is it happening:
This is part of regular maintenance to keep systems up-to-date.
