take with no argument seems very out of place to me. I think most Rails devs would expect it's alias, first.
find_by simplifies this a bit more though.

Switching to double quotes is preferable over escaping the embedded single quote.

Matching the url against URI's regexp helper gizmo is somewhat duplicative with your check in original_url_starts_with_http_or_https. I wonder how we can remove the duplicated concept. 🤔

I suspect Net::HTTP is capable of raise many other errors. I'd switch to rescuing all subclasses of StandardError with bare rescue and make sure only Net::HTTP code is invoked in this method. (just the URI.parse and the get_response parts)
