Hi @JeffBooth ,
it is indeed a combination of bad weather in Namibia (it's their rainy season), combined with some specific issues of the Sigma. Once a system does not ping for several days it gets marked as "offline".
Regrettably, it seems that in Namibia we are chasing several issues with several systems: The mount of the FSQ106 is not moving anymore, at the same time the inverters of the dome of the TI450 also stopped working. Potentially they both got hit by an electrical surcharge, anyway we do have to fix these things and it takes time. Luckily, in a way, weather is preventing useful observations mostly...
