For those looking to secure their systems from external source failures, I'd recommend taking a look at Sonatype's Nexus Repository [1]. It supports a wide range of package sources and has the option to self-host.
I almost didn't know that Github was down the other day because all the packages I was using were already cached on Nexus.
