Tuesday, September 4, 2012 - 15:30 to 20:30
Power supply of University Library and some parts of UPM was halted because of maintenance, according to Meralco

Additional Info: According to the security guard on duty, power supply has been re-established at least 5:00pm onward. I have a class during that time and was unable to re-establish the internet connection and the servers immediately. I went back to UPM before 9:00pm.
