I've often been experiencing this problem before that websites just don't open and the same message comes on Mozilla that usually appears when internet is not on. I have to keep clicking "Try Again" and eventually it works out after 2-3 tries. But in some cases, it can take a lot more than that.
My dropbox had also not been working due to this very problem. It never managed to connect to dropbox server and I had to actually activate a proxy just to sync all my dropbox files. Thankfully, dropbox is finally working alright today atleast, after days of trouble.
I understand that these problems are a side effect of the mass-censorship implemented by ptcl but the scale at which I'm experiencing it is just unreal. These days, even mirc can occasionally take about 3-4 tries to get connected. Is anyone else experiencing these problems?
