It looks like it may be related to the tracking being stripped that @AOU implemented. Possibly, anyway. Your OP link is: https://rwmalonemd.substack.com/p/monkey-pox&s=r Archive of that link is: https://archive.ph/aGkgN It shows it as redirecting to this link without the /p/ in the link: https://rwmalonemd.substack.com/monkey-pox&s=r However, archiving the link you posted in your comment strips the &s=r from the link: https://rwmalonemd.substack.com/p/monkey-pox https://archive.ph/L77qW But archive redirects that link to the full link you initially posted in the OP (*but with a ? and not an & symbol): https://rwmalonemd.substack.com/p/monkey-pox?s=r EDIT: Actually, it may not be due to the stripping as the proper link to the page is a ?s=r and not an &s=r at the end of the link. Somewhere the ? is switched to an & symbol, which isn't the valid address (if it needs any of that on the end in the first place, so it is likely just archive being dumb with its redirect for me).
