Documentation: Vendor specific pairing instructions hosted on their site - backuped?

[SVNKoch]

Just looked at some devices e.g. EnOcean Button and noticed that they link to a vendor page for specific pairing instructions (in this case to Instructions on vendor page).

I just thought about that it would be a bummer if these pages get removed. Could you mirror them / automatically add them to the internet archive? (Just did for it for these instructions: archived page)
