For your reference, this is information about the downtime that was posted the week preceeding the downtime:
EEE will be unavailable for scheduled systems maintenance for two days at the end of the Winter quarter, on Friday (3/29) and Saturday (3/30).
We recognize this is a significant disruption right before the start of the Spring 2013 quarter, and we carefully considered the importance of this update and its timing.
Why is this maintenance necessary?
The work we will be completing is critically necessary due to advanced hardware age and end-of-support for both the hardware in question and its operating system. If this work is not completed, we risk partial or full data loss requiring significant downtime of unknown duration, with uncertain results.
Why will this maintenance take so long?
To avoid file corruption and/or data loss during this process, it is necessary to have a full downtime (with no changes occurring to any EEE data) and we are estimating two days to complete the work and allow for adjustments for any unexpected issues that may arise.
Why were these dates, Friday (3/29) and Saturday (3/30) selected?
While we recognize how disruptive it is to have EEE unavailable right before Spring instruction begins, we have identified Friday (3/29) and Saturday (3/30) as the least disruptive two day period in which to perform this work because it will be 1) after Winter instruction, 2) after Winter grade submission, 3) over a holiday and weekend, and 4) before Spring instruction begins.

Are class mail lists affected?
Yes, class mail lists will be impacted by the two-day downtime.
Class mail list messages are routed through UCI mail services, then EEE servers. If you send a class list message during the two day downtime, it will bounce back to you from UCI mail services with an error. UCI mail services will periodically attempt to resend it, generating an additional error each attempt, until the EEE servers are available and the message goes through successfully.
While messages sent during the maintenance should ultimately go through, to avoid the bounce notifications, we recommend waiting to send any class mail messages until the system maintenance is complete, which it is expected to be by the end of the day Saturday, meaning your mail lists should be available in the morning on Sunday, 3/31.
