I've been meaning to ask this for a while now, but I've never got round to doing it...
Networks often only keep a show page (or even entire domain if it's separate) whilst the show is still airing / has products coming out / etc and not always forever, or if your looking for more information on say air dates, it may only specify the re-runs & future dates.
A solution to this is to use the internet archive (IA) to view what was on the site at different dates/times that it was crawled. I do this quite frequently to verify data (normally when people/databases disagree with each other).
My question is, for a defunct site (one that no longer loads), how does TVMaze want it entered here? Here's a few options:
1. Enter in the dead site - for historical purposes; if other people want to, they can use the IA themselves
2. Enter in a link to a snapshot of it from the IA - which is in the format: https://web.archive.org/web/date & time/website
3. If another network aired it later and has a functioning page for it, use that... though that would go against the current FAQ
4. Don't enter in any website at all
