(Apologies if this message isn't in your language.) 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 this wiki. There will be some times when the site will be in read-only mode, and there may be full outages; the current target windows for the migration are January 22nd, 23rd and 24th, 2013, from 17:00 to 01:00 UTC (see other timezones on timeanddate.com). More information is available in the full announcement.
