We've identified a bug in Fleet Server 9.5.3 (also present in 9.4.6) that can cause Elastic Agents to crash-loop and go offline when Fleet pushes a configuration update, including enrollment, a policy change, or a routine revision bump. This only affects policies that use Fleet's remote Elasticsearch output feature. Recommendation: If you use Fleet's remote Elasticsearch output, do not upgrade to 9.5.3 or 9.4.6 until a fixed version is available. If you're already on an affected version and experiencing agent check-in failures, contact Support for remediation steps. A fix has been merged and

What to do next
- Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
- Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.
- Watch the provider going forward. Follow Elastic Cloud's status feed →
GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
