Narrative:

At XX20Z the radar alarm went off (meaning we were going to lose the radar again) and soon after we lost total radar. The supervisors here at san juan call it a blink. This so called blink lasted about 30 seconds to 1 min. I was working only 5 aircraft, 2 of which were climbing and descending. I told everybody radar contact lost and instructed everyone to remain at hard altitude. After about 1 min, the radar returned and I idented everyone. Nothing out of the ordinary, said 1 supervisor. These so called blinks have been happening ever since I've been here (3 yrs). I believe they're getting worse and worse.
