I'll say that what I've seen of SLAs makes them pretty close to worthless, they 
tend to be partial credit based on the outage, but they only cover the cost of 
the service itself, so any payment you get ends up being a drop in the bucket 
compared to what you lose by being down.

Not to mention that SLAs commonly exclude planned outages, and I've seen that 
abused extensively.

However, the photos show these spheres of 'teleports' which probably use something higher than Ku.  I dont know what freqs these teleports use; and dont know either whether the Community gateways will use that Ku, or use the D-band (120-170GHz) recently reserved by 'ESSAFI II for starlink at ITU.
