CUDA Driver API documentation inaccessible (!)

Recently, I’m getting intermittent “Access Denied” messages when trying to access the CUDA Driver API online documentation. The common pattern is that I would be allowed to see the main page, but if I click on a section, either the style sheet won’t be applied, or it’ll be complete “Access Denied”. When this happens I can’t even click the PDF link - that gives me “Access Denied” as well.

Have any of you been experiencing something similar or is my ISP cursed? :-(

Everything seems to be functioning normally for me (ISP: Comcast; Location: California; Browser: Firefox). Download of the PDF works as well. I would suggest clearing browser caches and trying again.

I am assuming your ISP is not located in Iran, North Korea, or any other country on the US embargo list.

To me it sounds like you downloaded files/htm/html/cfm from the internet, and windows is blocking this by default, try giving permission to the files/folders by properties somewhere, you ll see it.

If this is not the case post link here so we can try as well.

So, this is still happening. My ISP is not in Korea or Iran or what-not; and it’s not a caching problem - the numeric code on the “Access Denied” page gets updated; and I am not using downloaded files, I’m using the online-URL. Also - I don’t use Windows, I run Devuan GNU/Linux.

Here’s some output from LiveHTTPHeaders - this time for a page in the Runtime API documentation:

… and I’ll mention again this is intermittent, not consistent.

Since the Akamai CDN is used, it is likely that different physical servers are involved when you and I, repectively, access the NVIDIA content, unless you also happen to be located in California.

A quick Google search seems to indicate that various people have encountered “403 Forbidden” issues when trying to access content delivered via Akamai from AWS instances. I assume that is not a scenario that applies in your case.
