(Im not sure where to file this type of issue in Phab :/)
While investigating T74674, I found that http://nan.wiktionary.org/ redirects to https://incubator.wikimedia.org/wiki/Wt/nan?goto=mainpage , which says:
```
Min Nan Chinese Wiktionary
A Wiktionary in this language does not yet exist.
```
But that is not true; we have one, over here:
https://zh-min-nan.wiktionary.org/
----
Likewise http://minnan.wiktionary.org/ redirects to https://incubator.wikimedia.org/wiki/Wt/minnan?goto=mainpage , which says
```
Error: This page is [[https://incubator.wikimedia.org/wiki/Incubator:PREFIX|unprefixed]].
```

Along the same lines, http://zh-min-nan.wikinews.org/ redirects to https://incubator.wikimedia.org/wiki/Wn/zh-min-nan?goto=mainpage , and http://minnan.wikinews.org redirects to https://incubator.wikimedia.org/wiki/Wn/minnan?goto=mainpage ; and both targets says
```
Error: This page is [[https://incubator.wikimedia.org/wiki/Incubator:PREFIX|unprefixed]].
```
http://nan.wikinews.org/ redirects to https://incubator.wikimedia.org/wiki/Wn/nan?goto=mainpage , which says
```
Min Nan Chinese Wikinews
A Wikinews in this language does not yet exist.
```
----
We also have an open wiki at https://zh-min-nan.wikisource.org/ , but https://minnan.wikisource.org/ and https://nan.wikisource.org/ redirect to https://wikisource.org/wiki/Main_Page
----
Then for Wikiquote, we have a closed wiki at http://zh-min-nan.wikiquote.org/ , but http://nan.wikiquote.org/ goes to https://incubator.wikimedia.org/w/index.php?title=Wq/nan/Th%C3%A2u-ia%CC%8Dh&redirectfrom=infopage , which is a typical incubator landing page.
http://minnan.wikiquote.org/ redirects to https://incubator.wikimedia.org/wiki/Wq/minnan/Th%C3%A2u-ia%CC%8Dh , which says:
```
Error: This page is unprefixed.
