Recently, I started to see a lot of connection timeout errors from my web browser at home (218.53.17.*). The web browser was basically trying to access the resources under the following domains:
.. which means I have to wait for very long time until a web page is rendered completely if the web site uses Gravatar or WordPress login service. Of course, the gravatars are all broken.
I also found that some of the servers that serve http://www.wordpress.com also give me connection timeout errors: (I got these IP addresses by querying DNS server manually. More specifically, 'nslookup http://www.wordpress.com')
Because the operating system randomly chooses one of the IP addresses on the list, sometimes it works and sometimes it fails with connection timeout.
What's interesting is that I don't have any problem connecting to the addresses mentioned above when I'm not at home. Therefore, I believe my IP address (or the IP block I belong to) has been blocked by someone between my home and WordPress.com.
I contacted my ISP to see if they can find out why, but I also thought it might be a good idea to ping the folks at WordPress.com.
The blog I need help with is trustin.wordpress.com.
