You are unlikely to attract anyone's attention by assigning things to @admin

Could you provide examples of pages that shouldn't be on the list? Note that it's cached as stated above the page.

Thank you Krenair, and thank you Glaisher. Please note especially this part of the conversation https://en.wikipedia.org/wiki/Wikipedia_talk:Special:DeadendPages#Deadend_Pages_Broken.3F which I posted above. An example of a page listed as dead-end is number 1 on the list https://en.wikipedia.org/w/index.php?title=Alternative_Tea which you can see is a working link. also number 2 https://en.wikipedia.org/wiki/Arnaud_Leclercq and number 7 https://en.wikipedia.org/wiki/Carnwath_Farms_Historic_Site_%26_Park and many many more on the list. Hope this helps narrow down the problem.

All three examples by Bulgarios are invalid. Those pages really were dead ends when https://en.wikipedia.org/wiki/Special:DeadendPages was cached 04:11, 23 June 2015.
I posted a series of real examples at https://en.wikipedia.org/w/index.php?title=Wikipedia:Village_pump_%28technical%29#Dead-end_pages

Thank you for re-opening this task Krenair and my apologies Krenair for not realizing the cache does not update as quickly as I expected.

Many thanks to PrimeHunter for pointing out the other cases which illustrate the problem is real nonetheless.

Please edit the task summary and replace "broken" by a description of the actual problem. "broken" can mean a lot of things. Thanks. :)
