Wikimedia sites to move to primary data center in Ashburn, Virginia
Next week, the Wikimedia Foundation will transition its main technical
operations to a new data center in Ashburn, Virginia, USA. This is intended
to improve the technical performance and reliability of all Wikimedia
sites, including Wikipedia.
Engineering teams have been preparing for the migration to minimize
inconvenience to our users, but major service disruption is still expected
during the transition. Our sites will be in read-only mode for some time,
and may be intermittently inaccessible. Users are advised to be patient
during those interruptions, and share
case of continued outage or loss of functionality.
The current target windows for the migration are January 22nd, 23rd and
24th, 2013, from 17:00 to 01:00 UTC (see other
Wikimedia sites have been hosted in our main data center in Tampa, Florida,
since 2004; before that, the couple of servers powering Wikipedia were in
San Diego, California. Ashburn is the third and newest primary data center
to host Wikimedia sites.
A major reason for choosing Tampa, Florida as the location of the primary
data center in 2004 was its proximity to founder Jimmy Wales’ home, at a
time when he was much more involved in the technical operations of the
site. In 2009, the Wikimedia Foundation’s Technical Operations team started
other locations with better network connectivity and more clement
weather. Located in the Washington, D.C. metropolitan area, Ashburn offers
faster and more reliable connectivity than Tampa, and usually fewer
The Operations team started to plan and prepare for the Virginia data
center in Summer 2010. The actual build-out and racking of servers at the
colocation facility started in February 2011, and was followed by a long
period of hardware, system and software configuration. Traffic started to
be served to users from the Ashburn data center in November 2011, in the
We reached a major milestone in February 2012, when caching servers were
set up to handle read-only requests for Wikipedia and Wikimedia content,
which represent most of the traffic to Wikipedia and its sister sites. In
April 2012, the Ashburn data center also started to serve media files (from
Cacheable requests represent about 90 percent of our traffic, leaving 10
percent that requires interaction with our web (Apache) and database
(MySQL) servers, which are still being hosted in Tampa. Until now, every
edit made to a Wikipedia page has been handled by the servers in Tampa.
This dependency on our Tampa data center was responsible for the site
outage in August
when a fiber cut severed the connection between our two locations.
Starting next week, the new servers in Ashburn will take on that role as
well, and all our sites will be able to function fully without relying on
the servers in Florida. The legacy data center in Tampa will continue to be
maintained, and will serve as a secondary “hot failover” data center:
servers will be in standby mode to take over, should the primary site
experiences an outage. Server configuration and data will be synchronized
between the two locations to ensure a transition as smooth as possible in
case of technical difficulties in Ashburn.
Besides just installing newer hardware, setting up the data center in
Ashburn has also been an opportunity for architecture overhauls, like
incremental improvements of the text storage
and the move to an entirely new media storage
keep up with the growth of the content generated and curated by our
Wikimedia’s technical infrastructure aims to be as open and collaborative
as the sites it powers. Most of the configuration of our
publicly accessible, and the Wikimedia
allows contributors to test and submit improvements to the
sites’ configuration files.
The Wikimedia Foundation currently operates a total of about 885 servers,
and serves about 20 billion page views a month, on a non-profit budget that
relies almost entirely on donations from readers.
Three days left! This is also about new user groups and thematical
organisations for individual projects, so forwarding.

>> Organizations ("affiliates" in short) and approving them when they are
>> ready is looking for about 6 new members.
>> The main focus of AffCom is to guide groups of volunteers in forming
>> affiliates. We make sure that the group is large enough to be viable
>> (and advise them on how to get bigger), review bylaws for compliance
>> with the requirements and best practices, and advise the Board of the
>> Wikimedia Foundation on issues connected to Chapters, Thematic
>> Organizations and User Groups.
>> This requires communication with volunteers all over the World,
>> negotiating skills and cultural sensitivity and the ability to
>> understand legal texts. We try to get a healthy mix of different skill
>> sets in our members.
>> Key skills/experience that we are looking for in candidate members,
>> are typically:
>> * Excitement by the challenge of helping to empower groups of
>> volunteers worldwide
>> * Willingness to work in a sometimes bureaucratic, sometimes political
>> * 4 hours per week availability
>> * International orientation
>> * Very good communication skills in English
>> * Ability to work and communicate with other cultures
>> * Strong understanding of the structure and work of affiliates and the WMF
>> * Communication skills in other languages are a major plus
>> * Experience with or in an active affiliate is a major plus
>> With the help of the Affiliations Committee, 2012 has been an exciting
>> year of transformation for the movement with the introduction of new
>> types of affiliation. This means that the workload of the Committee
>> has increased and diversified and help is wanted! Currently many
>> applications to become a Chapter, Thematic Organization or User Group
>> are in the pipeline and can use your attention and dedication!
>> You can send your applications with your name, contact data (e-mail,
>> wiki username), experience and motivation to join to the AffCom email
>> address, affcom AT lists DOT wikimedia DOT org by January 12, 2013.
>> You will get a confirmation that your application came through.
>> Members are usually selected every twelve months for staggered two
>> year terms. The applications will be considered by the current members
>> and outgoing members and Committee advisers, who are not seeking
>> Since I will be a candidate for re-selection myself, this process will
>> be managed by another committee member, Lodewijk Gelauff. I hope for
>> many suitable applications. If you have any questions, please don't
>> hesitate to email me or Lodewijk privately. We are happy to chat or
