https://www.cpdn.org/cpdnboinc/server_status.php does not seem to be available. I have not been able to view the server status webpage for quite a while.

It is here
http://climateapps2.oerc.ox.ac.uk/cpdnboinc/server_status.php
and the links that have gone from the left hand side can be accessed by going to the main page the link for which is at the bottom of this and other pages.

I like the new look and the more informative server status page.

Hi James

cpdn, like the rest of the university, is shifting to more secure settings.

The url that you posted is correct, as the new secure page, (you can tell these by the first part of the url, which is now https, but pages may or may not be available from time to time, as the upgrade progresses.
My guess is that a lot of the changes will occur "after hours".

(The front page link is currently working.)

I apologize for the late reply, but I have been very busy.

I found that accessing the server status webpage usually succeeded when I used the link on the home webpage and have not tried a direct link since finding this work-around. While testing I tried the direct link, which failed, then the link from the home webpage, which succeeded. I believe that the home webpage sets a cookie that the server status webpage requires.
