The Wikimedia Foundation <https://foundation.wikimedia.org/wiki/> will be
testing its secondary data centre. This will make sure that Wikipedia and
the other Wikimedia wikis can stay online even after a disaster. To make
sure everything is working, the Wikimedia Technology department needs to do
a planned test. This test will show if they can reliably switch from one
datacenter to the other. It requires many teams to prepare for the test and
to be available to fix any unexpected problems.
They will switch all traffic to the secondary data centre on *Tuesday,
September 1st 2020*.
Unfortunately, because of some limitations in MediaWiki
<https://www.mediawiki.org/wiki/Manual:What_is_MediaWiki%3F>, all editing
must stop while the switch is made. We apologize for this disruption, and
we are working to minimize it in the future.
*You will be able to read, but not edit, all wikis for a short period of
- You will not be able to edit for up to an hour on Tuesday, September
1st. The test will start at 14:00 UTC
BST, 16:00 CEST, 10:00 EDT, 19:30 IST, 07:00 PDT, 23:00 JST, and in New
Zealand at 02:00 NZST on Wednesday September 2).
- If you try to edit or save during these times, you will see an error
message. We hope that no edits will be lost during these minutes, but we
can't guarantee it. If you see the error message, then please wait until
everything is back to normal. Then you should be able to save your edit.
But, we recommend that you make a copy of your changes first, just in case.
- Background jobs will be slower and some may be dropped. Red links
might not be updated as quickly as normal. If you create an article that is
already linked somewhere else, the link will stay red longer than usual.
Some long-running scripts will have to be stopped.
- There will be code freezes for the week of September 1st, 2020.
Non-essential code deployments will not happen.
This project may be postponed if necessary. You can read the schedule at

*Technical Wishes: FileExporter and FileImporter become default features on
The FileExporter and FileImporter  will become default features on
August 5th, 2020 on all Wikis. They help you to move files from your local
Wiki to Wikimedia Commons, while keeping all original file information
(description, source, date, Author, and revision history) intact. The wish
to make moving files from local Wikis to Wikimedia Commons easier
originates from WMDE’s 2013 Technical Wishes survey. There it was voted
into the top wishes for technological improvements by the German-speaking
How does it work?
Step: If you are an auto-confirmed user, you will see a link “Export to
Wikimedia Commons” in the menu on the local file page.
Step: When you click on this link, the FileImporter checks if the file
can be moved to Commons. These checks are performed based on the wiki’s
configuration page which is created and maintained by each local wiki
Step: If the file is compatible with Commons, you will be taken to a
preview page on Wikimedia Commons, where you can update or add information
about the file, such as the description. You can also add the ‘Now Commons’
template to the file on the source wiki by clicking the corresponding check
box on the preview page on Wikimedia Commons. Admins can delete the file
from the local Wiki by clicking the checkbox ‘delete file on source wiki in
my name’. By clicking on the ‘Import’ button at the end of the page, the
file is imported to Wikimedia Commons.
If you want to know more about the FileImporter extension or the Technical
Wishes Project , follow the links. We are looking forward to answering
your questions and getting your feedback on our central feedback page .
