- 写入或调试 CodeQL 的新查询
GitHub 高级支持 customers can use the GitHub 支持门户 to report issues in writing, in English.
GitHub 高级支持 is available 24 hours a day, 7 days per week. If you purchased GitHub 高级支持 prior to September 17, 2018, support is limited during holidays. For more information on holidays GitHub 高级支持 observes, see the holiday schedule at "About GitHub 支持."
For tickets you submit, support is available 24 hours a day, 7 days per week. The initial response time guaranteed by the SLA is dependent on the priority level of the ticket. Response time begins when GitHub 高级支持 sets the priority level of the ticket. A response does not mean the issue has been resolved.
|Ticket priority level||Initial response time|
为确保 GitHub.com 稳定，必须安装并实施 GitHub Enterprise Server 发行版。 安装 GitHub Enterprise Server 发行版可确保您有最新功能、修改和增强，以及功能的所有更新、代码更正、补丁或 GitHub Enterprise Server 的其他一般更新和修复。
You must install the minimum supported version of GitHub Enterprise Server pursuant to the Supported Releases section of your applicable license agreement within 90 days of placing an order for GitHub 高级支持.
When you contact GitHub 高级支持, you can choose one of four priorities for the ticket: 紧急, 高, 普通, or 低.
|紧急||Production workflows for your organization or enterprise on GitHub Enterprise Cloud are failing due to critical service errors or outages, and the failure directly impacts the operation of your business.|
|高||Account or security issues with your organization or enterprise on GitHub Enterprise Cloud are causing limited impact to your business.|
|普通||Members of your organization or enterprise on GitHub Enterprise Cloud are experiencing limited or moderate issues with GitHub.com, or you have general concerns or questions about your organization or enterprise.|
|低||You have a question or suggestion about your organization or enterprise on GitHub Enterprise Cloud that is not time-sensitive, or does not otherwise block the productivity of your team.|
|紧急||GitHub Enterprise Server 在生产环境中出现故障，并且该故障直接影响您的业务运营。|
对 紧急 优先级事件单的支持服务只以英语提供。
|高||GitHub Enterprise Server 在生产环境中出现故障，但对您的业务影响有限。|
|普通||您在 GitHub Enterprise Server 方面遇到了有限或普通问题，或者对于实例运行有一般性疑虑或问题。|
|低||您对于 GitHub Enterprise Server 有问题或建议，但并不紧迫，或者该问题不影响团队的生产力。|
GitHub 高级支持 may consider a ticket solved after providing an explanation, recommendation, usage instructions, workaround instructions, or by advising you of an available GitHub Enterprise Server release that addresses the issue.
If you use a custom or unsupported plug-in, module, or custom code, GitHub 高级支持 may ask you to remove the unsupported plug-in, module, or code while attempting to resolve the issue. If the problem is fixed when the unsupported plug-in, module, or custom code is removed, GitHub 高级支持 may consider the ticket solved.
GitHub 高级支持 may close a ticket if the ticket is outside the scope of support or if multiple attempts to contact you have gone unanswered. If GitHub 高级支持 closes a ticket due to lack of response, you can request that GitHub 高级支持 reopen the ticket.
