Observe the path,
not a verdict.
A bounded one-time preflight for a single public origin and up to five relative paths. Results are retained only in this page’s memory as observations—not an up/down declaration or a live monitoring service.
USE IT TO: Use immediately before or after a controlled release to collect a small, explicit observation set and hand live status work to SID.
Bound the question.
Send one public HTTP(S) origin and one to five relative paths to the bounded SIU preflight. Do not enter credentials, private routes, customer identifiers, or sensitive query strings.
Not up or down.
An HTTP response from a bounded check is a point-in-time observation. It does not establish availability, uptime, customer impact, or a root cause.
- Results stay only in this open page’s memory.
- HTTP status requires context; it is not a product-health verdict.
What was returned.
Read these entries with the release context and approved customer-path verification. They are cleared when this page is refreshed or left.
Work the next known step.
- Provide one public HTTP(S) origin and from one to five relative paths. The server-side preflight receives exactly that bounded request and applies strict target-safety checks.
- Keep the returned observations in the open page only. Record any necessary follow-up in the team’s approved internal system, not in this public interface.
- Interpret response observations alongside release context, authentication boundaries, caching, geography, and customer reports. Escalate live concerns to SID and the team’s incident process.
Confirm each submitted path is relative to the supplied origin and is safe to observe without credentials.
Compare an observation with the intended customer journey and the release record before making a decision.
Use the SID destination and the team’s approved response workflow for ongoing or customer-impacting status work.
Source notes, not borrowed certainty.
Planning basis: MDN Fetch semantics and OWASP SSRF safeguards
- MDN — Window.fetch() ↗MDN notes that a fetch promise resolves when a response is available and does not reject solely for HTTP error status; response status still requires interpretation.
- OWASP — Server Side Request Forgery Prevention Cheat Sheet ↗OWASP recommends strict target validation, careful DNS handling, private-address rejection, and redirect controls for server-side requests.
Authorship: SIU Enablement editorial draft; source-bounded operational guidance. Reviewed by: Release owner and platform owner approve the selected paths and any interpretation of results. Revalidate: Revalidate the observation set when routing, authentication, hosting, or customer journeys change.
