Remember the network? Long before "infrastructure as code", container orchestration, cluster management, or death by 1,000 clicks in some labyrinthine cloud configuration console, the network was an essential layer (or 3) of IT operations. The fact is that the network - good old route, switch, packets, and flow networking - is alive and kicking and more important than ever to anyone who cares about the performance and availability of our applications.

More to the point, the network holds secrets you'll never find in the traces, events, metrics, and logs of typical application observability solutions. Secrets like:
- The very real performance issues that happen between the parts you control and the end user (and how to address them)
- Ways a content delivery network - something intended to speed up user experience - can fail silently but horrifically.
- Knowing not only how much data is flowing through the network, but what that flow is comprised of
- Updated versions of old but trusted techniques that actually work in modern networking contexts.

In this talk I'll reveal the observability secrets hiding in plain sight within your network; suggest ways to access that information; and highlight the insights and value you're missing if that data remains invisible, unused, or ignored.
