According to a tipster (and from Matt’s blog), WordPress.com was not supposed to be blocked, but one of the blogs. It had to do with a military officer which led to a court order. TTNet, the main telecommunication’s company, complied with the order, but some inexperienced employee blocked the whole WordPress.com domain instead. He soon realised and took action to fix it.
The employee, according to the tipster, is about to leave his job.
