I work as tech-support at a college campus and last evening the power to the entire campus went out. Due to this I got to go home early from work which is nice, but for the students and teachers that had classes it probably wasn't a good thing.
The month of May is the tail end of the semester therefore missing a single class period can be detrimental to things like presentations and tests - especially for classes that only meet once a week (which classes in the evening tend to be). For sure students in lower level courses likely couldn't care less (I'd be happy as a fox), but I'd be pissed if I were a graduate student and it was my day to present thesis.
Today a professor shared with me that a student of his was due to perform for his final masters last night but the blackout torpedoed that plan. What made it worse was his parents flew all the way here from Russia for the occasion. Dreadful.
The University needs to be responsible for the lost instruction time. Students pay good money for tuition and to have power outages cancel class without recompense of say adding an extra day is unjust. Last evening's incident wasn't even the first one this calendar year!
Though I guess we can't rule out the possibility that last night someone really didn't want to take a final and did some grade A sabotaging to the power-grid to avoid it.
