Narrative:

Our new ASR 9 radar system failed. The ARTS targets started 'CST' coasting in all sectors. ARTS targets would randomly fly off the targets in different directions, causing a lot of confusion. I'm not sure that I maintained separation during this event. But I think so. While maintenance and supervisors tried to restore the old ASR 8 system we were without primary radar for about 2-3 mins. Once the ASR 8 system was on line everything was normal.
