The CDL mainframe server is getting a new network interface designed to improve response time and stability when the system is heavily used and thus, our IP address is changing.  If you use domain names, e.g., or, to access our CDL-hosted databases via telnet or Z39.50, then this change will be transparent.  If you must use numeric addresses, then you will need to change the numeric address from to our new address, when we make the cutover.

Our cutover date is June 30, 1999, at 2:00 a.m.  If there are any changes to this date we will notify you via this list.

If you experience connection problems after this date, please check with your local library systems or computer support staff.  If they cannot assist you in resolving the problem, call the CDL Helpline at (510) 987-0555.

Please share this information with your colleagues.
