Yeah, and the non-technical users will surely understand that what they need to do when the link doesn't work is:
1. Recognize that it's an Archive.org URL
2. Understand that the link references an archived page whose URL is "clearly" referenced as a parameter
3. Edit the URL (especially pleasant on a cell phone) correctly and try loading that
If you expect the user to be able to go through all this trouble if the Archive is down, you can also expect them to look up the page on the Archive if the link does not load.
