You may remember that the Technology department did a major test in April 2016 to see how well they could recover from a major disaster.  During this test, it was not possible to edit Wikipedia or any of the other WMF wikis for about 30 minutes on two days.

They are repeating this exercise this year.  This will affect editors and contributors around the world, at Wikipedias, Wiktionaries, Wikivoyages, Commons, and other WMF sites.  Please translate the main announcement into as many languages as possible.  Last year, we had complete translations into about 40 languages, and partial translations into a couple of other languages.

This should be a relatively quick translation job.  The main change from last year is the dates and times.  I have just checked (by creating part of the German translation), and about 60% of the sentences are identical to last year and stored in translation memory.  

(Also, if you read German, please review the parts of the German translation that I copied.  :-)

If you have questions, you can reach me in e-mail or on wiki.[1] 

THANK YOU!
