I do not know the answer to this question. When Staff reactivate the support link you can contact them. Here’s the link http://en.support.wordpress.com/contact/ After you use the searchbox at the bottom of the page there will be a section that says “Have you found the answer to your question?” You can choose either “Yes I found the answer to my question.” or “No I didn’t find the answer to my question and I would like to contact support for help.” The no option will reveal the contact form.
I don’t know whether they are blocking it now, but there have been earlier threads started by bloggers located in Kazakhstan who said they were not able to get to their blogs. You might want to do a search of the forums for that and try to contact those posters to see whether they’ve any information on access to wp.com blogs.
