Extended technical
support for IBM z/OS

Help optimize uptime with access to specialists
with deep IBM® z/OS® expertise

Keeping your IBM z/OS up and running is critical to your business. If your z/OS environment has reached end-of-service, or if you are considering migrating to the next supported version but need more time—you can’t afford a single minute of downtime.

IBM can provide extended technical support for IBM z/OS. We offer two services—defect support and usage support—to give you robust coverage of your end-of-service z/OS environment. Usage support helps you gain remote access to “how to,” diagnostic and usage questions. Meanwhile, defect support can help you recover from virtually any z/OS problems you might encounter. Whatever your needs—we provide around-the-clock remote access to Severity 1 support that you can rely on.1

1Severity1 support is needed when your systems are inoperable.
