From Don’t Block the Blog:

It has being widely reported throughout Pakistan that access to the entire blogspot.com domain has yet again been blocked in Pakistan. For about four months (since May, 2007) Google fortunately had changed the IP address of its Blogspot servers. The new IP addresses were not demarcated as prohibited by the censorship filters located at the Pakistan Internet Exchange. Today, for some odd reason, Google has suddenly reverted back to its original IP address, which has been on the block list since March of 2006.
