The software which we use to run this site - dokuwiki - needs to use some cookies in order to function. You can read about those on their FAQ page. Blocking these will prevent the site functioning properly, so they are classed as strictly necessary by the GDPR.
Our understanding is that unless you log into the wiki then no persistent cookies will be set, only a PHP session cookie which is cleared when you quit your browser. Simply browsing publicly accessible sites should not involve this server setting a persistent cookie.
Standard server logs containing IP addresses and request details are kept on the machine which hosts this site. These are currently only used for performance measurement and debugging, in line with QUB standard policies.
