I haven't seen a thread on this, but move it about if necessary. I shouldn't be the one to start the thread because, well, I don't have enough background right now.
However, some Farsi wiki people told me that Iran blocked access to Commons, and reports are that some other nations in the region did the same. The different Middle Eastern languages are losing access to Commons which is making things very hard for them.
Looks like the WMF will have to get rid of the people standing in the way or they will be collapsing sometime soon. I would like to see what they do with Greg Maxwell, as he has been using his ops and connections in the #wikimedia-commons IRC room to try and disrupt Jimbo's attempts to fix Commons anyway he can.
