Amazon WorkSpaces Connection Health Check¶
What it is¶
Amazon WorkSpaces Connection Health Check is a public-facing AWS diagnostic web page (clients.amazonworkspaces.com/Health.html) that measures round-trip-time (RTT) from the visitor's browser to each AWS region and displays which region is the recommended (lowest-RTT) one for a WorkSpaces session.
It is intended for end users troubleshooting WorkSpaces client connectivity, but it has become a de-facto public RTT reference that engineers can use to anchor RTT numbers to their own location.
Why it shows up in timeout guidance¶
Zalando's timeouts post cites the page as a calibration anchor for the "derive connection timeout from measured RTT" discipline:
"You can also look at Connection Health Check by Amazon. This is what I get from my local machine, RTT 28 ms to the recommended AWS Region." (Source: sources/2023-07-25-zalando-all-you-need-to-know-about-timeouts)
The 28 ms number is the author's measured RTT to their recommended region, cited verbatim as a grounding example for the RTT × 3 heuristic.
Why this is useful for wiki / documentation¶
Many timeout discussions cite RTT numbers without a way for the reader to verify them from their own context. The WorkSpaces Health Check page provides:
- A public URL that doesn't require an AWS account.
- Per-region RTT values measured fresh.
- A "recommended region" signal that reflects routing conditions at test time.
Zalando's inclusion of the specific 28 ms number from this tool is an example of using a public, reproducible measurement as a grounding citation instead of a hand-waved RTT estimate.
