I'm running a script I wrote to detect all dead links, will report back with the results once it's done

Edit:

I'm fine with merging without fixing these, I'll open an issue with all dead links for the whole site once v4 & v5 have been merged. This is just a preview in case one of the link updates was broken:

# looks like I need to dedupe based on redirections
