+# Rollback Report
+
+This report documents the rollback process, its reasons, actions taken, and outcomes.
+
+## 1. Executive Summary
+
+[**Placeholder: Briefly summarize the reason for the rollback, the actions taken, and the overall outcome. Was the rollback successful? Are there any ongoing issues?**]
+
+*Example: A critical bug was discovered in version 2.5.0 of the application. A rollback to version 2.4.0 was initiated. The rollback was successful, and the application is now stable. Further investigation into the bug in version 2.5.0 is underway.*
+
+## 2. Rollback Trigger
+
+### 2.1. Reason for Rollback
+
+[**Placeholder: Describe in detail the reason for initiating the rollback. What specific issue or incident triggered the decision?**]
+
+*Example: After deploying version 2.5.0, users reported intermittent server errors (HTTP 500). Monitoring dashboards showed a significant spike in error rates and a degradation in application performance.*
+
+### 2.2. Severity Level
+
+[**Placeholder: Indicate the severity level of the issue that triggered the rollback.**]
+
+*Possible values: Critical, High, Medium, Low*
+
+*Example: Critical*
+
+### 2.3. Impact Assessment
+
+[**Placeholder: Describe the impact of the issue on users, services, and the business.**]
+
+*Example: The server errors were preventing users from completing critical transactions, impacting revenue and user satisfaction. The incident also affected the availability of a key API used by partner applications.*
+
+## 3. Rollback Procedure
+
+### 3.1. Rollback Plan
+
+[**Placeholder: Outline the planned steps for the rollback. Include specific versions, scripts, and commands used.**]
+
+*Example:
+1.  Verify the integrity of the previous version (2.4.0) backup.
+2.  Stop the current version (2.5.0) deployment.
+3.  Deploy the backup version (2.4.0).
+4.  Run database migrations to revert to the previous schema (if applicable).
+5.  Verify application functionality and performance.
+6.  Monitor system logs for any errors.*
+
+### 3.2. Rollback Execution
+
+[**Placeholder: Document the actual steps taken during the rollback process. Note any deviations from the original plan and the reasons for those deviations.**]
+
+*Example: The rollback was executed as planned, with the exception of a minor issue with database migration scripts. A slight modification was made to the script to ensure compatibility with the current database state. This was documented in the database migration log.*
+
+### 3.3. Rollback Time
+
+[**Placeholder: Record the start and end times of the rollback process.**]
+
+*Example:
+*   Start Time: 2024-01-26 10:00 UTC
+*   End Time: 2024-01-26 10:45 UTC*
+
+### 3.4. Personnel Involved
+
+[**Placeholder: List the individuals involved in the rollback process and their roles.**]
+
+*Example:
+*   John Doe: Lead Engineer
+*   Jane Smith: Database Administrator
+*   Peter Jones: Operations Engineer*
+
+## 4. Post-Rollback Analysis
+
+### 4.1. Verification of Rollback Success
+
+[**Placeholder: Describe how the success of the rollback was verified. Include specific tests and monitoring metrics used.**]
+
+*Example: After the rollback, application functionality was tested using automated integration tests and manual user acceptance testing. Monitoring dashboards showed a return to normal error rates and application performance.*
+
+### 4.2. Root Cause Analysis (Initial)
+
+[**Placeholder: Provide an initial assessment of the root cause of the issue that triggered the rollback. This may be a preliminary investigation and may require further analysis.**]
+
+*Example: The initial investigation suggests that a recently introduced code change in the payment processing module caused the server errors. Further code review and debugging are required to pinpoint the exact cause.*
+
+### 4.3. Corrective Actions
+
+[**Placeholder: Outline the planned corrective actions to prevent similar issues from occurring in the future.**]
+
+*Example:
+1.  Conduct a thorough code review of the payment processing module.
+2.  Implement more robust unit and integration tests for critical code paths.
+3.  Improve monitoring and alerting to detect issues earlier.
+4.  Implement a canary deployment strategy for future releases.*
+
+### 4.4. Lessons Learned
+
+[**Placeholder: Document any lessons learned from the rollback process. What went well? What could be improved?**]
+
+*Example:
+*   The rollback process was well-documented and executed efficiently.
+*   The monitoring dashboards provided valuable insights into the issue.
+*   The communication between teams was effective.
+*   Areas for improvement:
+    *   Improve the speed of database migrations.
+    *   Automate the rollback process further.*
