Welcome to our CoreStack Technical Support guide, where customer satisfaction is our primary objective! This Technical Support guide is backed by a team of trained and experienced support engineers that are there to assist you. With Operations in the USA and India, we provide our customers with 24×7 support for your critical issues.


To make sure your request is prioritized correctly, we have established service request severity levels and a definition of each level. When you contact us, you will be asked to assign your request a severity level.

  • Severity 1 (S1): CoreStack is “down” or there is a critical impact to your operations. We will commit to work around the clock to resolve the situation. Expect all necessary resources and support from your team as well.
  • Severity 2 (S2): CoreStack performance is severely degraded, or you are unable to perform certain key functions which significantly affect your operations. We will commit to work continuously during normal business hours to resolve the situation. Expect all necessary resources and support from your team as well.
  • Severity 3 (S3): Functional issues that impact specific operation or users while most other operations remain functional. We will commit to work during normal business hours to restore service to satisfactory levels.
  • Severity 4 (S4): You require information or assistance with CoreStack product capabilities. There is little or no impact on your normal operations.



To submit a service request, you can send an email to [email protected]. This creates a ticket in our ITSM tool. The ticket will be triaged based on the severity and assigned to the respective L2 engineers to work on them.


Specifying the following info will help expedite your request:

  • Subject or Title to state the problem clearly
  • Severity Level of the issue (see definitions above)
  • Describe the issue with details on why the severity is assigned
  • Which page, what actions were being performed when you face the issue.
  • Error message or code if any. Screenshot is preferred


Our technical support team will provide you with an update and the ETA for resolution. However, you can always provide more information or request updates by replying to the email received from support.


Our resolution framework is described in the picture below. All requests will be triaged by the Level-1 Support team and they would try to resolve them based on Known Issues Database. Based on the severity of the ticket, the request will be escalated to Level-2 and Level-3 within the escalation window.

The Escalation Manager will be in loop for all escalations to L2/L3 and will facilitate the swift recovery of the system. Recovery will be the first priority which will ensure that the critical operations if any blocked are resumed. The team will then work on the root cause analysis and permanent resolution to ensure that the issue does not occur again.

Continuous updates shall be provided to the requester of the ticket. The requester can also contact the escalation manager if required to get further details on the resolution status.


Given below are the typical response times for various severity levels. Please refer your SoW / contract for the actual service levels agreed for the specific engagement. Response time will differ based on the support plan purchased.
