So there is more redundancy at 19E than 28E.
Also we don't really know what the state of health of 2A/B is apart from that they seem to be working right now. There must be something that caused the hurry-up that made them decide to switch from Proton to Arianespace (unless they think Proton is not reliable enough).
what i am about to say is based on my observation on the lead up to astra 2d getting took out of service quicker than expected. on the run up of 2d goign bye bye, i notice the power on 2d transponder swas dropping quite a bit from 92% down to 74% day before it went off air that was over i say 3-6 weeks with the last week seeing the fastest drop, what i have notice about 2a/b is they where 94% about 3 months ago now there about 91% and 2b i think ill need to double check the transponders to see if it is 2b, has drop to 89%, if anyone know what sat the Olympics channels are on it the other one that having the problem.
if we see transponders switching to astra 1n then i say that be a sign that the birds might be failing or at the very least less power, although i think Olympics might be on astra 1n instead of astra2 birds as i think the power might be higher on them not 100% ill need ot check, if the power is about 98% or more on my systems then that suggest it is 1n
