Different cache invalidation rules for similar users?

by Strainu

Hi, I've recently seen some complaints from 2 users located in the same country that it takes about half a day for the Javascript changes to propagate. Users from different countries but similar user rights don't seem to have this problem. Is it possible to have different cache invalidation rules for different countries? If not, what else could cause this behavior? Thanks, Strainu

Announcing www.wikimediastatus.net

by Chris Danis

Hi, The Wikimedia Site Reliability Engineering team is pleased to announce the launch of a new public-facing status page at https://www.wikimediastatus.net/ This site shows five automated high-level metrics where you can see the overall health and performance of our wikis' technical environment. It also contains manually-written updates for widespread outages, which are written as quickly as the engineers are able to do so while also working to fix the actual problems. The site is separated from our production infrastructure and hosted by an external service, so that it can be accessed even if the wikis are briefly unavailable, or if something is wrong with Wikimedia's connectivity to the Internet. You can read more about this project on Diff[1] and on Wikitech[2]. Feedback is welcome on the Wikitech talk page[3], on Phab[4], or on the #wikimedia-sre IRC channel[5]. Thanks!

Some of the referenced Phabricator tasks above _may_ still be private. Unfortunately, when security issues are reported, sometimes sensitive information is exposed and since Phabricator is historical, we cannot make these tasks public without exposing this sensitive information. If you have any additional questions or concerns regarding this update, please feel free to contact security(a)wikimedia.org or file a security task within Phabricator [3].

Hello, I will restart the Gerrit and CI services tomorrow Thursday April 7th at 7:00 UTC. The services will be unavailable for up to half an hour while the maintenance is being conducted. I have shifted the morning UTC backport and config window by half an hour. The MediaWiki train for 1.39.0-wmf.36 scheduled for 8:00 UTC might be delayed a bit depending on how many config and backports we have to process. Synchronization will be on Libera.chat IRC channel #wikimedia-operations cheers, -- Antoine "hashar" Musso

Give WMF Feedback on Model Cards

by Hal Triedman

Hi all, The WMF Privacy and Machine Learning Platform teams are developing model cards to increase visibility, transparency, and accountability of algorithmic decision-making on WMF platforms. A model card <https://arxiv.org/abs/1810.03993> is a document about a machine learning model that seeks to answer basic questions about the model in a clear and concise manner. The broad goal of this project is for every ML model hosted by WMF to have a model card for the community and public to understand, discuss, and govern that model. We would love for you to give some feedback on the talk page of our prototype: https://meta.wikimedia.org/wiki/User:HTriedman_(WMF)/Language_Agnostic_Link… We're specifically looking to answer the following questions: - What aspects of the model card are useful, informative, or helpful? - What aspects of the model card are confusing or unhelpful? - Are there any features or sections that aren't on the model card that you would like to see? Thanks so much! Hal

🚀 SD0001 receives Web Perf Hero award!

by Krinkle

I'm happy to share that the next Web Perf Hero award goes to SD0001, in recognition of their many contributions and positive impact on the performance of Wikimedia software. I'll share two major examples. SD0001 implemented Package files <https://www.mediawiki.org/wiki/ResourceLoader/Package_files> for Gadgets <https://www.mediawiki.org/wiki/Extension:Gadgets> (T198758 <https://phabricator.wikimedia.org/T198758>). This enables gadget maintainers to bundle JSON files, unpacked via `require()`. This improves performance by avoiding delays from extra web requests. It also improves security by allowing safe contributions to JSON pages, as pure data with validated syntax on-edit. Previously, admins on Wikimedia wikis for example, would need script editing access for this and rely on copy-paste instructions from another person via the talk page. SD0001 also introduced `Module::getSkins` in ResourceLoader, and used it in the startup module <https://www.mediawiki.org/wiki/ResourceLoader/Architecture#Front-end> to optimise away unneeded module registrations <https://techblog.wikimedia.org/2019/09/19/wikipedias-javascript-initialisat…>. We just shipped the first adoption of this for Gadgets (T236603 <https://phabricator.wikimedia.org/T236603>). In the future, we'll use this to optimise MediaWiki's own skin modules as well. This award is given once a quarter, and manifests as a Phabricator badge. More information and past recipients: https://www.mediawiki.org/wiki/Wikimedia_Performance_Team/Web_Perf_Hero_awa… Phabricator badge: https://phabricator.wikimedia.org/badges/view/17/ -- Timo Tijhof, on behalf of WMF Performance Team.
