The following message just arrived in my email:

At approximately 1:35 pm today, a contractor, working at a campus construction site, pulled down a utility pole and surrounding power lines. This caused a fire and a transformer to fail. Subsequently, many buildings on campus were without power. Power should be restored to most buildings on campus by close of business today. Please forward any ongoing problems related to this outage to the Physical Plant so that we may assist you. Thanks for your patience. We apologize for any inconvenience.

I think it pretty much speaks for itself.
