According to multiple local outlets, WordPress blogs are currently not accessible in Pakistan and pointing the blockage at the Pakistan Telecommunication Authority (PTA). TechCrunch has not been able to confirm that yet. As it stands right now, WordPress.com and blogs hosted by WordPress cannot be reached. Self-hosted WordPress blogs still work.
it is not surprising that Pakistan would block these sites. The government has a track record of blocking Twitter, Facebook and other Internest social sites.
