It seems strange that no one else is having having problems that we know about.
A couple of suggestions
Have you got someone nearby that you could ask to try and access the forum from their computer ? Just to see if it's something in your area that causing the problem.
What software are you running on your computer ? have you an alternate browser on it you could try? Have you checked it recently for malware?
Can you try this link when you can't access the forum http://www.downforeveryoneorjustme.com/gn15.info
There are some more diagnostic tools we could run, but we will see if these give us any clues.
To know the meaning of life you need not to be dealt a good hand, but rather to play the worthless hand you have been dealt to the best of your ability.
