In addition to Grani.ru, EJ.ru, Kasparov.ru, and Alexey Navalny's LiveJournal blog  [Global Voices report], today some ISPs also blocked the website of the liberal radio station Echo Moskvy (Moscow's Echo). According to antizapret.info , the website was blocked at the behest of the Attorney General's office because it contains a mirror of Alexey Navalny's blog at www.echo.msk.ru/blog/navalny. Echo Moskvy Deputy Editor-in-Chief Vladimir Varfolomeev tweeted that at least one ISP is working on resolving the problem:
Пресс-секретарь Акадо сообщил, что идёт работа по возвращению доступа к сайту Эха, но по-прежнему будет закрыта страница Навального на нём.

Akado's [ISP -ed.] press secretary told me that they are working on returning access to Echo, but Navalny's page there will still be blocked.
Some bloggers are also reporting [ru] problems accessing their LiveJournal blogs, likely because of the same issue of over-zealous blocking.
