Pi-Hole - The DNS Triangle

At the end of the day, I had Pi-hole running, but the setup was far from trivial. There were four or five cardinal problems, and none of these should have happened, because the installation wizard could have gone through separate checks to make sure things were working. Part of the first-time run could be the service check, and if there are issues there, some sort of self-diagnosis to make sure FTL is up and running. The same applies to the Web service. Then, there's the password reset and list update. All of these would make the experience much more streamlined.

As a product, Pi-Hole is a very nice and powerful tool. It does its job extremely well, it's fast, effective and robust, and the Web UI is nicely designed. You also gain some on the traffic side, as there's less content that needs to be served, and fewer queries to be resolved, hence performance improvement for the stuff that matters. The setup isn't trivial but it is achievable, and you have a lot of flexibility in how you wire up your network. You could have Pi-Hole as a standalone system, or it could serve all the different devices in your home. All in all, this is the doomsday weapon for if and when the Internet turns rogue on you. Well worth testing, but remember the second rule of thermodynamics. You can't have trivial and complex at the same time.
