This is a very funny thing. I am unable to open flock.com and wordpress.com and I have literally no idea why its hapenning. The other site I remember I tried to open was zimbara.com (spellings could be wrong. These sites simply timeout.
I had to download the flock browser using http://flock.com.nyud.net:8090/. I have no idea what the servers at nyud.net are doing with such huge amounts of traffic that they seem to generate. But it works and that is what really matters.
