The modem knows. Learning to read it separates link faults from network faults quickly.

Designing a hub and spoke that tolerates outages
Every remote site will lose its link. Design for what happens during, not just after.
Acceleration, and what it breaks
Performance enhancing proxies work well and complicate everything they touch.
Why voice over satellite needs different thinking
The usual voice quality rules assume terrestrial latency. Over satellite, half of them do not apply.
Rain fade and link budgets
The link degrades gracefully until it does not. Reading the margin tells you which side of that you are on.
TCP over long fat pipes
High bandwidth and high latency together defeat default TCP settings.
Latency you cannot engineer away
Geostationary orbit imposes a floor. Design for it rather than trying to tune past it.
Vendor defaults that will hurt you
Shipping defaults are chosen so the device works out of the box, not so it is safe.
Configuration backups that are actually restorable
A directory of config files is not a recovery plan. Here is the gap.
Junos commit and rollback: the feature worth envying
Configuration as a transaction changes how confidently you can work.
