Manual testing guide

@spatton and @Ejegg thank you for making it clear! Much appreciated!

We decided to use a json file containing a limited dataset instead of CDB. Also we decided to remove WANObjectCache

There is still one missing part - the banner is supposed to be displayed only on Minerva

The code used for the banner was partially taken from here https://phabricator.wikimedia.org/T361047#9839444 which was setup with "maximum impressions any individual will see" being 2.

@Etonkovidova sorry for the back and forth, but if you were testing on beta cluster - I think the fix was deployed after your test. Currently I can see the fix in Safari on beta cluster.

The changes of the patchset can be previewed here https://wikipedia25-portals-dev.toolforge.org/

Scenario 4 - for some reason, I don't see the baby globe in mobile mode. @ATitkov - do I need to do something special to see it on mobile?

Banner code

<script> 
    const CNContext = mw.centralNotice.kvStore.contexts.GLOBAL;
    const CNBannerKey = 'impression_diet_wp25eastereggs-minerva-launch-banner';
    const impressions = mw.centralNotice.kvStore.getItem( CNBannerKey, CNContext );

Thank you for the catch! This issue is reproducible on Safari. I will take care of it as soon as possible.

could there be a file for the beta cluster? and potentially one for test.wikipedia (with test wikidata)?

For example https://www.wikidata.beta.wmcloud.org/wiki/Q1 is not the same as @ATitkov https://www.wikidata.org/wiki/Q1

@Nintendofan885 thank you for the input! I was actually had the same concerns/questions, but did not have the capability to research and verify the domains/https availability. I will update those once I get the opportunity

@Etonkovidova thank you for raising this concern, indeed the WikiData integration has not been yet tested on beta cluster. It would be great if some sample articles could be exported from enwiki and the respective Qids mapped on beta cluster side.

The respective patchset was requested to me merged into the patchset of the ticket https://phabricator.wikimedia.org/T415353

The respective patchset was updated to include the fix for https://phabricator.wikimedia.org/T415355 and re-purpose configuration var Wp25EasterEggsEnable instead of creating a new one Wp25EasterEggsGlobalEnable.

Reproduction steps:

• While on Vector, with viewport width > 1120px, find and delete <div class="wp25eastereggs-sitenotice-landmark"></div>
• Resize the the viewport to width < 1120px. Normally the BabyGlobe would be moved to .wp25eastereggs-sitenotice-landmark but we deleted the div, so BabyGlobe should be just hidden
• Resize the viewport to width > 1120px
• The BabyGlobe should be moved back to the sidebar - the video is not playing.

The toggle in the screenshot allows each wiki language/community to enable/disable the "birthday mode" interventions to their wiki. So the wikis that opt in - will probably set this toggle to enabled before the official release date.

@ABorbaWMF Thank you so much for the testing, it's really appreciated! I will try to get the mentioned iOS versions and pin down the issue

I have tested the audio interviews and they were working for me on the following devices

• iPhone 12 mini, with iOS 26.2.1, Safari Chrome Firefox
• Simulator iPhone 17 Pro, with iOS 26.2, Safari

IIUC that is the expected behaviour. The sidebar has its own scroll bar, so that the controls inside of it remain kind of "sticky"

i wonder if the easiest approach is to just add the link via JS?

Hello everyone, sorry for not replying sooner to this ticket, I will have a look into it as soon as possible.

Not needed, as static media can be fetch by utilising wgExtensionAssetsPath

This is a screenshot of the modified CommunityConfiguration page for the WP25EasterEggs

This needs input from Reader Experience team. Currently Vector's clientPreferences.js does not support adding custom links in the Appearance pinnable dropdown.

Manual testing

IIUC this still awaits a deployment

Thank you both @Jdrewniak and @Volker_E for the support on this! I think this one can be resolved. I will create new tickets for the next steps

This has been fixed, deployed and verified. If changes occur, please reopen

manual testing

manual testing:
the video logo src should be https://.../assets/img/... and not https://.../assets/img/video-logo/... , also the video should be visible and playing

I know it might look too soon, but I want to request either scheduled re-deployments or the ability to deploy myself, in order to update for bugfixes and a couple of incoming i18n and media.

QA was successful. Some people report needed a refresh for the first visit on https://wikipedia25.org/ or https://www.wikipedia25.org/ but I don't think we can do something about it. (Please correct me if I'm wrong)

Manual testing:

• in desktop resolution click on "Who is hiding in the globe" button, you should be taken to the aforementioned url in a new window
• in mobile resolution click on the video logo, in the opened dialog click "Learn more", you should be taken to the aforementioned url in a new window

With some moderate additional effort I could reduce that "soft launch" time window to like 5 minutes. But please let me know if it you would like that.

1. Manual testing

@Jdrewniak Can you answer this question?

Sorry for the delayed rely...

I noticed the website just shows a Wikipedia icon and the website is not usable. When I set display: none for the <div id=splash> the website works normally. This effect can be seen locally and on the old toolforge site. I'm not sure if this is a second safeguard for the deployment in January. If it is, it's not really needed, as we are doing a switch using DNS. So the website is not really reachable before.

I will close this one and open a new task for the review requested fixes

To be honest I think this can be marked as done :)

In regards to the request that the site should be published at 8:30 UTC on Jan 15th 2026, I am wondering if we can use an apache based solution like the following

Would it be ok with you if we do that next week, on December 22nd?

Here are the replies I got back:

This can be marked as done. Here is the respective commit https://gitlab.wikimedia.org/toolforge-repos/wikipedia25-years-of-wikipedia/-/commit/bec74abf4e5dee219057df5b060e1be38b558184
