Broken links to apps?

I'm not sure if this is the right place to raise it, but I was recently trying to find the Magnetic Dipole Applet notebook through the geoscie.xyz website and Google, and most of the easy links were broken:

https://hub.gke1.mybinder.org/user/geoscixyz-gpglabs-r9lr8ydk/tree/Notebooks/MagneticDipoleApplet.ipynb at https://gpg.geosci.xyz/content/magnetics/magnetics_applet.html

https://notebook.community/ubcgif/gpgLabs/notebooks/mag/MagneticDipoleApplet.ipynb at https://notebook.community/ubcgif/gpgLabs/notebooks/index

I eventually found a working version here https://hub.gke1.mybinder.org/user/geoscixyz-gpglabs-ulpnehvn/notebooks/notebooks/mag/MagneticDipoleApplet.ipynb at https://gpg.geosci.xyz/content/appendix/apps.html
