Seems Facebook Server is Down
I have been trying to log in to the facebook for about half an hour but the server is not responding. The browser says that Server Not Found. At first I thought that my internet connection was causing the trouble. I checked and reconnected to the internet. But Facebook is not opening yet. Then I tried to open other webpages they are opening just good.
So, it seems that Facebook server is down, though I did not find any notification whether it was under any kind of maintenance. Hope the server will be up soon.
