Hi, all,
I'm pleased to announce that Tim has just enabled the Global Blocking
extension on all Wikimedia projects.
The global blocking extension allows stewards to block IP addresses
and ranges on all of Wikimedia's projects, a tool which has been
much-needed to deal with cross-wiki vandalism and spam. Policies for
use of global blocking were discussed on meta, and are presently
located at <http://meta.wikimedia.org/wiki/Global_blocking>. Global
blocks are not currently applied on meta, so that they may be appealed
there.
While the code has been quite thoroughly checked, any bugs should be
reported at bugzilla - a 'GlobalBlocking' component exists under the
'Extensions' product.
