I'd be happier if Malaysia just admitted that their radars were off/unserviceable at the time.
I've spent a lot of time on this and I think I've evaluated about every snippet of information that's available.
From all that I've learned, I am certain that the radar at Pulu Penang was up and running that night and it was a very capable phased array radar of the same variety that serves NATO for detecting incoming ballistic missiles. It was fully manned, or at least scheduled to have been so. I have no way of knowing if everybody (all four people) showed up for work that night. And while it may or may not have had someone observing the returns in real time, from the statements issued the morning after, it is clear to me that they had at least brought themselves up to date by viewing the stored data. They may (probably) did a replay for higher ups, possibly even before sunrise.
I am also of the opinion that Malaysia is hiding something, but that something is not radar function related IMO.
