Relocation of CM/ECF Email Delivery Servers

To All ECF Users:

The Court was recently notified that in August, the Administrative Office of the U. S. Courts moved the location of its CM/ECF email delivery servers to provide for better backup and recovery.  As a result of the migration, several new Mail server Internet Protocol (IP) addresses were assigned to the CM/ECF email delivery application.

Because the migration involved a network location move, we have been monitoring the bounce-back of NEF deliveries to ensure that the Internet Service Providers for our registered CM/ECF users are not blocking NEF deliveries from these new IP addresses.

We are unsure of the impact of this change but believe the majority of court users will be unaffected.  However, if you believe that you are not receiving NEFs, you should contact the ECF Help Support Desk immediately at (213) 894-2365.  Because the migration involved a network location move, if you are not receiving notices, you may need to contact your Internet Service Provider to have the new uscourts.gov Mail server IP addresses shown below whitelisted.
