For those who only read the headline and the comments: Five of SpaceX’s Starlink constellation satellites are set to come burning back through Earth’s atmosphere, _an unexpectedly low attrition rate_ following the company’s launch in late May.
I bet those 2 are also failures, but probably in other satellite subsystems. For example, if the solar panel only partially unfolded, there would be enough power to do a controlled descent, but not enough for useful service work.
Seems like it's doing well.
