Browser diagnostic

Network check

This check sends at most 12 requests to four fixed Relayfield paths on the same origin. It does not accept custom hosts, addresses, or ports.

Run a bounded check

JavaScript is required for the interactive check. Without it, this page still documents exactly what the tool checks.

Fixed targets

The target list is built into this page and cannot be changed by user input.

Static frontend

Checks the small static-origin health object.

Public API

Checks public service metadata.

Operational API

Checks whether the live status interface responds; its reported health is not overridden.

Resource delivery

Checks one published same-origin resource.

Current result

No diagnostic run has been started.

Need a bounded transfer sample?

The transfer check sends exactly one fixed same-origin sample of 256 KiB, 1 MiB, or 4 MiB and separates request latency from response-body transfer time.
