All,
As you may have read about in other venues, the Wikimedia Foundation will
be conducting a switchover of datacenters on September 11 and 12, with the
switch back to occur on October 10 and 11. During the switchover and
switch-back events, the wikis will be in read-only mode.
Cloud VPS and Toolforge are not affected by these switchovers. However, if
you run bots or scripts that make edits to the wikis, they may be unable to
make edits during this time. This should appear to your bots as the
standard read-only mode which occurs unplanned on the production wikis from
time to time.
Please let me know if you have any questions.
