<p>Yes wget seems suboptimal. The robust way is to clone the website off github (git@github.com:bitcoin-core/bitcoincore.org.git), so that you have a copy of the source code as well, then you can build it yourself.

Is there a more robust way to create a mirror exist now, other than `wget -mkxKE -e robots=off https://bitcoincore.org`?
