How is the relations between Squid and the SatBoost set up?

From your description it sounds like the SatBoost system is a parent to
Squid?

If so, possible causes include

* ICP query timeouts
* Non-hierarchical request types

Unless the SatBoost requires the use of ICP, I'd recommend using a
non-ICP parent peering relation.

cache_peer no-query option
prefer_direct off

This will send most request thru the SatBoost system. However some
non-hierarchical requests may bypass it. To overcome this you can use
the never_direct option, but then Squid will fail if the SatBoost system
fails.
