Technical Operations
Site infrastructure

Wikimedia Labs

A new dynamic proxy system has been deployed on Labs. This means that the admin of any project can arrange for public web access and a dedicated DNS hostname for a project instance without requesting an IP address. Labs staff and volunteers will now be reclaiming quite a few IPs as existing projects migrate to a dynamic proxy setup.

The WMF has hired a short-term contractor, Mike Hoover, to assist with the migration of Labs infrastructure from Tampa to our new datacenter in Ashburn. Mike has spent a lot of time exploring the existing infrastructure and running test setups; soon he will start to configure the new OpenStack nodes in production.

Andrew has been working on cleaning up stale and unused resources. He's working on some automatic documentation that will help users track the status of their projects and instances with an eye towards predicting the impact of the coming migration.

Labs suffered two brief outages: a brief, self-inflicted network failure, and a longer outage during which one of the virtualization hosts failed. Both outages were swiftly resolved, but there's a bit of lag as some tools and services failed to come back properly afterwards due to poor distribution of virtual servers (inter alia, both the grid master and the shadow (backup) master were on the same server).

Preparation for the move to the Ashburn data center is well in progress, with the new storage server being physically configured this week as well as the new hardware servers for user databases (including the new postgresql instance intended for OSM).

Kiwix
The Kiwix project is funded and executed by Wikimedia CH.



Wikidata
The Wikidata project is funded and executed by Wikimedia Deutschland.

The Wikidata developers held an office hour to give a status update and answer questions. The log is now available. In addition they worked on ranks, ordering of statements and the quantities datatype. The quantities datatype is needed to for example enter the number of inhabitants of a country in Wikidata. It is available for testing now on http://test.wikidata.org. Ranks will allow for certain statements to be marked as preferred or deprecated. This is for example useful to indicate a previous majors of a city or the number of inhabitants of a country in 1900.

Magnus Manske wrote a gadget that allows you to additionally show Wikidata search results when doing a search on Wikipedia. He also extended the Reasonator tool to now also work for cities. So far it only supported people and species.

Future

 * The engineering management team continues to update the Deployments page weekly, providing up-to-date information on the upcoming deployments to Wikimedia sites, as well as the annual goals, listing ongoing and future Wikimedia engineering efforts.
