+
+## Summary
+<!--
+Clearly state the scope of the problem, and how it affects GitLab.com
+-->
+
+
+## Impact
+<!--
+- Quantify the effect of the problem to help ensure that correct prioritization occurs.
+- Include costs to availability. The Incident Budget Explorer dashboard can help here.
+- Include the number of times alerts have fired owing to the problem, how much time was spent dealing with the problem, and how many people were involved.
+- Link to affected incidents, and cross-reference them as related issues.
+- Include screenshots of visualization from Grafana or Kibana.
+- Always include a permalink to the source of the screenshot so that others can investigate further.
+-->
+
+
+## Recommendation
+<!--
+Provide a clear, unambiguous, self-contained solution to the problem.
+-->
+
+
+## Verification
+<!--
+Provide a method for validating that the original issue still exists.
+
+Having a way of checking validity can save on a great deal of back-and-forth discussion between Infradev Triage participants including Engineering Managers, Directors and Product Managers and make space for other non-resolved issues to get scheduled sooner.
+
+Ideally, provide a link to a Thanos query or an ELK query and clear instructions on how to interpret the results to determine whether the problem is still occurring.
