We've had the broken Memory Alpha-links fixed directly on the database. Thank you, @Shog9 and @Catija.

Can we do the same for all Wikia links, since wikia.com has moved to fandom.com? There's a redirect in place currently, but we don't know for how long. There are far too many links to Wikia to edit them all by hand.

Can we request an update directly on the db to fix these?

And if so, can we make change http to https for these links where necessary?

    Might have to find someone else to do the change this time...

    As was mentioned on the linked post apparently some moved to wikia.org not fandom.com. Also if they’re updating from wikia to fandom in the db directly I don’t think it’d be a problem to do the https change either.

  • This SEDE query is by no means efficient or foolproof but it turns up approximately 700 unique wikia links with the most popular, starwars.wikia.com, being used 9083 times.

  • While they’re at it, there should also be HTTP → HTTPS. Jan 19, 2020 at 3:58
  • @Stormblessed that's a bit trickier, because not all sites work with https. We know the Fandom sites do, and I've added that to my request, but we can't do a blanket conversion, since ISFDb doesn't even work with https (yeah, I know it's 2020).

  • @SQB what I was saying is that if they are doing Wikia -> Fandom, they should do HTTP://{site}.wikia.com to HTTPS://{site}.fandom.com ; the RegEx for that wouldn't be super hard. Jan 19, 2020 at 14:55

    @Stormblessed oh, absolutely. It's the final line of my request.

  • @Valorum: I just wanted to add a relevant tag while I was looking at it. The [status-review] tag ensures it's been added to our internal tracker, so we'll assess the request and then post an answer here once we decide how to proceed.

Unfortunately, while I recognize the importance of the change, there is not currently quite enough information here to proceed. This change affects ~28,000 links across the network. I am able to locate some official documentation about wikia.com's move to fandom.com, so I'm not worried about the majority of these cases. However, as TheLethalCarrot notes:

As was mentioned on the linked post apparently some moved to wikia.org not fandom.com.

There are a few open questions in my mind:

  1. Does a mass link edit risk breaking any historical links?
  2. Does a mass link edit risk pointing at the wrong target for some subset of links? (If so, how will they be identified?)
  3. Will a mass link edit make it harder to manage other issues like possible link rot in the future?
  4. Is this change necessary to do right now, given that the redirects still work?

In part, I have these questions because the distribution of Wikia links is quite long-tailed. If there are problems migrating some subset of these Wikia links, that could be a problem. Just on scifi, this is the cumulative distribution of which wikis are referenced (click through for detailed chart):

Distribution of Wikia links

This is a quick and dirty query so there are a couple spurious entries, but still, it takes the top 93 wikis to cover ~90% of posts. 95% coverage raises that to 211 wikis. 99% coverage raises that further to 542 wikis. So it's not as though we're dealing with a tightly-clustered number of wikis... it's quite varied.

Though it's not strictly necessary for us to run the update network-wide, it's also worth noting it's quite long-tailed in the sites it could affect, and if run network wide it will change links on some sites folks might not otherwise expect:

  • Arqade: 7041 matches
  • Anime: 2840 matches
  • Stack Overflow (yes, actually): 2307 matches
  • Movies & TV: 1739 matches
  • Worldbuilding: 747
  • RPG: 669
  • Super User: 367
  • Board & Card Games: 273
  • Vi and Vim: 261
  • ... ELU, Photography, Unix & Linux, Ask Ubuntu, Puzzling, Mathematics, Physical Fitness, Game Development, Writing, Travel, Bricks, ELL, and Japanese Language all have >50 links affected.

In order to proceed with this change, we need to know:

  1. That the scope of the change is well-characterized and understood.
  2. That places the change breaks (or could break) posts have been assessed and are well-documented.
  3. That the community has, very broadly, acknowledged and accepted any cleanup work that is going to need to take place after the replacement network-wide, or confirmed no such cleanup work is needed.

The reason we need this information is because there's simply no going back. I mean it. After we hit that button, any reversion constitutes either a ton of developer work, or the collective work of the network to clean up all affected posts. And it may become very difficult to separate posts needing cleanup from posts that are OK as-is.

For smaller changes, this kind of post would be generally fine to proceed on and touch up later as needed. For a change affecting ~28,000 links across a half dozen sites, there simply is no reasonable way to reverse or correct this change if it is a mistake for any nontrivial number of links. So, we'll need to be sure that work was done to verify the change is non-breaking.

Once y'all have double checked and are sure this doesn't pose serious risks, mods: feel free to kick this back into and we can take a look at it again.

  • Thank you for the detailed analysis and write up! I completely understand the concerns; some pages haven't just moved from wikia to fandom, some have changed from something like Ancestral_Plane to Ancestral_Plane_(Fuertonas), so imo it might be a good idea to hold off for the time being (as long as the redirect still works!)
