McMaster "Power Failure" - Library Closed

Well, I am on campus cause I decided to go to the library. Everything seemed normal on campus. The library was lit up like normal and there were people in the lobby. It was not till I got to the doors that I realized this is a “power failure” and the library is closed. The people in the lobby, the staff of the library by the looks of things. Anyway, it has been 25 minutes on the library is still closed so I figured I take a picture of the “power failure” as you can see the lights are all on. Gee, this higher education is confusing!
Some Power Failure eh?
And yes, okay the power was out at one point but that does not mean that things are closed after it comes back on.
