I’m grinding on the new Networking for System Administrators so here’s a chunk.
Ultimately, the Internet is a bunch of routers, switches, firewalls (however you define them), and other devices that connect a tangle of cables. Once a client request traverses the local WiFi connection, it travels through a bunch of wires and devices until they reach your server. Ultimately, every Internet node is connected by wire that can be traced from the local café to downtown, where it joins a bigger cable that goes across the country, perhaps joining a huge cable that runs under an ocean or three to reach another continent. That huge cable gets broken up into finer and finer wires until it finally reaches the cheap CAT5 that connects the server to the patch panel. Some parts of this link might run over satellite connections or carrier pigeons or who-knows-what. Every one of these components is fragile.
It’s a miracle the Internet works. At all.
When I finish this draft and get the book to tech review, sponsorships will close. If you want your name in the book or the challenge coin, grab it now. And when the Laserblasted print arrives in my store, I’ll be reading one last tibdit from it. If you prefer ebook you can get it now.
