Today, the Russian Federal Service for Supervision in the Sphere of
Telecom, Information Technologies and Mass Communications instructed all
Russian internet providers to block all user access to Wikipedia. All
involved parties are aware of the development. I am not sure whether
only
ru.wikipedia.org will be blocked, or all WMF projects. In the
latter case, if you are going to travel to Russia, you will need to gen
an IP exempt flag in advance in the projects you are going to edit.
Cheers
