Account and Contact Information

In order to help you, GSS requires your account information to customize their support, as well contact information to get back to you. When you contact GSS ensure you have your:
  • Red Hat customer number or Red Hat Network (RHN) login name
  • Company name
  • Contact name
  • Preferred method of contact (phone or email) and contact information (phone number or email address)

Issue Severity

Determining an issue's severity is important to allow the GSS team to prioritize their work. There are four levels of severity.
Severity 1 (urgent)
A problem that severely impacts your use of the software for production purposes. It halts your business operations and has no procedural workaround.
Severity 2 (high)
A problem where the software is functioning, but production is severely reduced. It causes a high impact to business operations, and no workaround exists.
Severity 3 (medium)
A problem that involves partial, non-critical loss of the use of the software. There is a medium to low impact on your business, and business continues to function by utilizing a workaround.
Severity 4 (low)
A general usage question, report of a documentation error, or a recommendation for a future product improvement.
For more information on determining the severity level of an issue, see
Once the issue severity has been determined, submit a service request through the Customer Portal under the Connect option, or at Note that you need your Red Hat login details in order to submit service requests.
If the severity is level 1 or 2, then follow up your service request with a phone call. Contact information and business hours are found at
If you have a premium subscription, then after hours support is available for Severity 1 and 2 cases.
Turn-around rates for both premium subscriptions and standard subscription can be found at
