Cambridge Structural Data System (CCDC) moved to new hardware

The CCDC system has been moved to new, more powerful hardware. IMSS has changed the campus DNS to point ccdc.caltech.edu to the new machine, but it may take a while for the change to propagate.

If you get a message that ‘account is currently not available’, you are still pointing to the old server. You may use the following temporary address to reach the new server: ccdc2.library.caltech.edu.

Please note that if you are using an IP address to connect to CCDC, the current IP is 131.215.225.16 (not 131.213.225.25).

If you find any problems with the CCDC software on the new server, please contact Betsy Coles (bcoles AT caltech.edu).
