Or just stop using them completely? ;)

May be the question to ask is do we really need that?

I don't know any way to get the number of tried resolutions (or views) of a non-existent domain.

If someone find an old Wikimania website they may think the current website is wikimania2020.wikimedia.org

@Bugreporter: What does a namespace on a wiki have to do with a subdomain?

I am just here doing clinic duty for the SRE tag. Traffic should decide on this ticket, but based on my (limited) understanding of our setup, I suggest we should not do this unless there is a really good reason to.

@Bugreporter suggestion seems to be related to pageviews of wikimania2020 vs. other wikimanias, if that is the case probably the fix should be on analytics reporting per page or namespace, not on actual domain setup (and maybe that is even possible already). Please let us know what your needs are so maybe we can suggest a different way to achieve the same.

But again, I am not the person to decide, traffic should.

So maybe first T202684#5735025 should be answered before we do anything here?

The swap of Traffic for Traffic-Icebox in this ticket's set of tags was based on a bulk action for all such tickets that haven't been updated in 6 months or more. This does not imply any human judgement about the validity or importance of the task, and is simply the first step in a larger task cleanup effort. Further manual triage and/or requests for updates will happen this month for all such tickets. For more detail, have a look at the extended explanation on the main page of Traffic-Icebox . Thank you!

Since Wikimania since 2019 lives under https://wikimania.wikimedia.org/wiki/<year>:Wikimania, can this be closed or is there some desire to continue these redirects?

Hard to tell because every year the organizers of Wikimania are different people. But from experience this does tend to come back every year and most of the time they are desired.

It's a bit bizarre to want them since wikimania.wikimedia.org should default to the latest upcoming conference, wouldn't it?

In the past each Wikimania had its own wiki. I think that's where that comes from. They used to be individual wikis. And each Wikimania has a totally different group of people who organize them. They mostly wanted a fresh wiki and not work on the previous one.

But now that there's a single wiki, isn't the idea of having domains with the year on them moot?

Please see the child task T202684#5735025. This task has the status stalled as it's blocked on T202684. No need to fragment more discussions here. :)

@Aklapper, Thanks for linking that. I'm still confused as that seems to be another task entirely: That one is about importing older wikis into a unified wiki whereas this one is about creating redirects for upcoming (well, three years ago upcoming) wikimania events. Since the wikimania events are now under that singular wiki, I see no reason to create any further redirects!

@BCornwall: Argh, and you are absolutely right about the future aspect that I somehow failed to realize. Sorry (and thanks).

I propose to decline this task.

The subtasks may be more important. Once all per-year wiki are migrated we can redirect all of wikimania20\d\d.wikimedia.org.

I propose not to redirect all of wikimania20\d\d.wikimedia.org, see previous comments.
