I have checked around and it is not only me who is experiencing this, other people in my area are also having this problem. Same here in the office, only everything Google is accessible, others are not. I hope this problem would be resolved soon by my ISP.
There is something wrong with my ISP, I could not access the internet except those pages that are under Google like the Google search engine, Blogger, and my Google Apps. Other pages do not load. So I could not check my Hotmail email, PPP, Social Spark, and all those money makers 🙁
