Severity classification

Severity 1 ("Sev-1")
Critical business impact

A Severity Level 1 issue is a critical production error within the Software or ClickHouse Cloud that severely impacts the Customer's use of the Software or ClickHouse Cloud for production purposes, such as the loss of production data or where production systems are not functioning and no work-around exists. ClickHouse will respond to Severity Level 1 issues within one hour during Normal Business Hours, and implement continuous follow-the-sun case management during applicable Normal Business Hours to provide a workaround or resolution for any Level 1 issues as soon as is commercially reasonable.

Severity 2 ("Sev-2")
Major business impact

A Severity Level 2 issue is an error within the Software or ClickHouse Cloud where the Customer's system is functioning for production purposes but in a reduced capacity, such as a problem that is causing significant impact to portions of the Customer's business operations and productivity, or where the system is exposed to potential loss or interruption of service. ClickHouse will respond to Severity Level 2 issues within four hours during Normal Business Hours, and use reasonable efforts to provide a workaround or resolution for any Severity Level 2 issues.

Severity 3 ("Sev-3")
Minor business impact or general questions

A Severity Level 3 issue is a medium-to-low impact error that involves partial and/or non-critical loss of functionality for production purposes or development purposes, such as a problem that impairs some operations but allows the Customer's operations to continue to function. Errors for which there is limited or no loss or functionality or impact to the Customer's operation and for which there is an easy workaround qualify as Severity Level 3. General questions are also Severity Level 3 issues. ClickHouse will respond to Severity Level 3 issues within one Business Day during Normal Business Hours, and use reasonable efforts to provide a resolution for any Severity Level 3 issues in a subsequent release of the Software or ClickHouse Cloud, as applicable. All inbound production email cases shall have an initial status of Severity Level 3.
