Qlik Cloud® – US East (N. Virginia)

Summary of Impact:

From April 8 to April 11, 2026, customers utilizing the Qlik Cloud US-East-1 (North Virginia) region may have experienced intermittent service disruptions. Primary observations included delays in application reloads, login failures, and “Internal Server Error” messages. While these issues were observed in the user interface, backend processes remained functional and executed as expected. 

Root Cause: 

The investigation attributed the incident to two primary factors: i) database resource contention that delayed processing of reloads and authentication requests; and ii) a configuration mismatch impacting tenant accessibility. 

Remediation: 

Qlik Engineering responded by immediately increasing database capacity and deploying an emergency configuration patch. To ensure long-term stability, we improved database infrastructure segregation to prevent future database resource contention and applied performance optimization enhancements to reduce system latency.  

We apologize for any inconvenience this disruption may have caused and are committed to delivering the reliable experience our customers expect from Qlik Cloud.
