April 1st, 2016:
The CACTUS web server has been migrated to a significantly reconfigured system on new hardware (with a new IPv4 address). The HTTPS protocol has been enabled for all services. HTTP has been permanently turned off on March 31st, 2016. http:// requests will from now on be redirected to the corresponding https:// request. If you encounter any bugs or behavior different from the old server, please let us know immediately.
