For about a week now I have been experiencing a lag spike at one minute intervals at lasts about 2-4 seconds and spikes as high as 1500ms ping and as low as 900ms. It really only affects real time PC games like League of Legends.

Out of a 20 minute game, 16 events occurred with about an average of once per minute. There were three instances of no lag around the 45-50 second mark of the minute but this could be due to human error only one instance I can guarantee was not error and no event present. This test has been repeated to the same extent, the time varies but the interval does not; usually every minute.
Wireless does not make a difference, I have tested my connection with an ethernet cable and I still get the same lag event with no real sign of change.
