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.

SLA is basically a guarantee from the provider that a particular level of
service will be met. Failure means penalties.
There's a single community gateway in Unalaska. The customer is Optimera.

I don't think the idea of advertising with the association of fiber is only
about latency.
Think "symmetrical link" which isn't common even for Enterprise satcom.
IT is true. That symmetrical aspect - upload speed similar to download
bandwidth, compared to a higher ratio ul/dl - is a great benefit in fiber and
ADSL for home users. Maybe the latency ratio could also be considered.
Also the SLA. Wonder if we can test this link somehow. How performant is it vs
the Ku Band service? Anyone has a connection to the customer?
I suppose it is not yet possible to compare the SLA of starlink Community
gateways, since the starlink Community gateways seem not to be deployed
already. But I dont really know.

PS:
I am not sure what you mean by the SLA aspect (service-level agreement). Maybe
you mean a form of higher reliability and stability of the user link.
Ku band (12GHz-18GHz) is what typical starlink uses to end users.
Starlink Community gateways might also use Ku band, I think. 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.
Then there is this Starlink Direct which promisses data (maybe higher
bandwidths?) to unmodified smartphone users in year 2025, which might also be
used for communities, albeit much smaller ('tethering' WiFi technology). That
is at 2.6 or 3.6 GHz (unmodified smartphones).
JIOSpace fiber seems to be at MEO altitudes and also for unmodified
smartphones,, hence around 2.6 or 3.6GHz.
Do you think the 'SLA' of smartphones is high?
