The first part just seems like a forced MITM situation whilst the second makes some sense - in a cyber warfare scenario; however, that runs under the assumption that the DNS servers and/or entries didn't get poisoned before they're "cut-off" from foreign infrastructure. Doesn't really seem all that worthwhile, unless you create recovery points to ensure that you have records to recover with; otherwise, what's the point...?
(Of course, I could be entirely misunderstanding the premise of the law because it's not referenced in the article and I can't speak/read Russian for feck-all...)
