/reports/* routes to the api host through the site's own distribution, so a shared match is a lance.blue link. Its cache key includes the query string: a report is asked for from a point of view and in one of several card layouts, and Managed-CachingOptimized drops both. Origin 5xx are no longer cached. A report answers 503 while its match is still being fought, and CloudFront's ten second error floor would hold that past the point where the report exists.
