I have finally got my selfhost wiki up to a satisfying shape. Its here: https://wiki.gardiol.org
Take a look i hope it can help somebody.
I am open to any suggestions about it.
Note: the most original part is the one about multi-homed routing and failbacks and advanced routing.
That’s true. But it doesn’t take away the possibility to use them in a selfhosted environnement.
Large enteprises like facebook and google still use them, but they have the backing to secure them safely.
Also, there is always the possibilty to add all subdomains in one certificate which takes away the wildcard subdomains.
