Macbook unable to access some websites.

[Ewan]

Hi i hope this post is in the right subforum.

So my problem is my computer is seemingly unable to access certain websites.
I don't think its a browser issue as the same websites are unavailable to me on all three browser is try to use: Chrome, firefox and safari.
The first website this happened on was the guardian, i read that sometimes their ban-hammer over extends its reach and i thought perhaps they were blocking my IP or something.
However now i cannot connect to jstor and it reads the same message:

Oops! Google Chrome could not connect to www.jstor.org
Try reloading: www.jstor.org

Jstor is perhaps my prime research source so i need to access this website i have tried accessing it through a vpn but Jstor blocks that kind of access.

This problem only arose say 4 months ago and before that i could access this websites fine.
Has anyone heard of such problems before, know how to deal with them?
I thought perhaps it may be to do with plugins extensions on my browser but at least the ones i've found haven't made a difference

My computer is a 4 year old macbook running 10.58.

Many thanks in advance
Ewan

Loads fine here on Safari 6.1

Perhaps you might have solve the issue but sometimes DNS setting can cause this behaviour. On my Mac I was unable to access several sites till I changed my DNS, which now works fine.
