Clear cached cgi-sys/defaultwebpage.cgi.redirects

Hi, I accidently redirected browsers to the default-page: /cgi-sys/defaultwebpage.cgi for the domain for a while (more than a week) and it seems like these are 301-redirects that are cached in the browser. Is there any way to make these cached redirects to go to the actual website now without clearing each individual browser's cache?
