I cannot access drupal.org I haven't been able to access drupal.org for the past few days. When using Chrome I get: 'This webpage is not available'.  I have no problems with accessing any other site.

Oddly enough when I use a proxy I have no problem. I've cleared my cache in both IE and chrome but still no luck. I don't believe my IP address has been blacklisted so beyond that I don't know. This is true when I try on my phone too so perhaps it is IP address related?
For what it is worth here is a link to Chromebook help for "This webpage is not available".

Assuming you've typed in the right URL, it looks like Chrome will give you this error message if it thinks the site takes too long to respond.  The help page also suggests:


Clear your cookies.
Adjust your proxy settings


You could also try to use another browser to access the site (both Firefox and MSIE work OK for me).
