Here are the latest e-mails that I have received. These definitely concern the SETI web site, but I don't know how the server is routed.
<About today's outage>
Connectivity from evans to SSL was lost again last night, from about
2:30am to 6:30am. It has been restored, and we'll continue to monitor
today. Sorry for the inconvenience, and thanks for your patience.

<About Saturday's outage>
Today, there was an unscheduled outage affecting Space Sciences
Lab, Lawrence Hall of Science, and the SETI@home program. This
outage lasted from about 9:30 AM until 8:00 PM and was caused by
scheduled construction work that disabled an undocumented section
of fiber that linked the abovementioned sites with campus.
Fortunately, additional strands of fiber cable were run along a
different pathway to the same sites. However, it took three CNS
staff members a considerable amount of time and energy to route
the appropriate links over the new fiber. We were able to restore
connectivity around 8pm as mentioned.
The current setup is rather temporary, and we will be working over
the next several weeks to make a more permanent transition to the
newer fiber. The "old" fiber link will be restored as
well. There may be some minor outages as we make these
transitions; however, those will be pre-announced.
