30 Minutes Scheduled Tools Harbor Downtime 2025-08-19
by Raymond Ndibe 19 Aug '25

19 Aug '25

On Tuesday next week tools harbor will be readonly for maintenance reasons, for a duration of 30 minutes. This means that you will be unable to run new build-service builds, but you should be able to run jobs using already existing images. The expected duration is from 13:00 UTC - 13:30 UTC. _______________________________________________ Cloud-announce mailing list -- cloud-announce(a)lists.wikimedia.org List information: https://lists.wikimedia.org/postorius/lists/cloud-announce.lists.wikimedia.…

Breaking change: Removal of rc_type and rc_new fields from recentchanges table
by Amir Sarabadani 18 Aug '25

18 Aug '25

Hello, As part of improving performance and stability of the recentchanges table, we are addressing some tech debt. rc_new field was deprecated 13 years ago and rc_type similarly was deprecated 11 years ago. We are moving forward with dropping these columns in favour of rc_source field. If you're querying rc_new or rc_type, please switch to using rc_source instead. They will be removed from wikireplicas in a week. This would allow us to consolidate several different indexes on this table and improve performance of Special:Recentchanges and Watchlist plus simplifying MediaWiki code. To follow the work, you can check https://phabricator.wikimedia.org/T400696 and related subtickets. Thank you and apologies for the inconvenience Best -- *Amir Sarabadani (he/him)* Staff Database Architect Wikimedia Foundation <https://wikimediafoundation.org/>

Debian 13 "Trixie" now available on Toolforge and Cloud VPS
by Taavi Väänänen 13 Aug '25

13 Aug '25

The Debian project released the latest version of their operating system, version 13 or "Trixie", last weekend.[0] The new release is now available for both Toolforge and Cloud VPS users. On Toolforge, the following new pre-built images[1] take advantage of the new runtime versions in Trixie: * trixie (base image for compiled languages) * jdk21 * mono6.12 * node20 * perl5.40 * php8.4 * python3.13 * ruby3.3 On Cloud VPS, a new "debian-13.0-trixie" image is available following the usual naming scheme. Now is also a good opportunity to start migrating VMs running Debian 11 ("bullseye") to newer versions, as we will be starting the proper deprecation process for that in the near future and creation of new Bullseye VMs is now restricted. Note that any new VMs you create will now get IPv6 connectivity by default, see [2] for more details.

Toolforge upgrade to kyverno 3.3.9 tomorrow at 10:00UTC
by David Caro 12 Aug '25

12 Aug '25

Hi! We are working on upgrading one of the critical components of toolforge k8s[1], and we will be rolling it out tomorrow at 10:00UTC on toolforge production. There's no downtime expected, though upgrading this component specifically has proven bumpy in the past, so we recommend to not run critical loads during that time. I'll reply to this email when starting the upgrade and when finishing it. Thanks!

PAWS downtime 2025-08-04
by Andrew Bogott 04 Aug '25

04 Aug '25

On Monday next week we plan to expand the volume that stores PAWS notebook files. PAWS will be down during the resize, possibly for as long as an hour. We are not planning to change the current restrictions on PAWS file usage for individual notebooks, but this expansion will allow us to support ongoing growth in usage without needing to purge existing old and large-sized notebooks. The resize will begin around 14:00 UTC.
