Public internet IP address and hostnames are changing for the IBM servers that support internet delivery of fixes and updates for customer system's software, hardware, and operating system.

This change pertains to all operating systems supported by IBM Electronic Fix Distribution (EFD) / IBM Fix Central system.

Customer action may be required to ensure uninterrupted fix delivery services.


New network connections between your machine and IBM servers are required to keep your ability to order and download fixes and updates for your system's software, hardware, and operating system.

You must configure your firewall and proxy server if you have a firewall in your network, or if your machine must use a proxy server to access the internet.
