How does this work?

Your browser makes HTTPS requests to link Google Cloud Run services deployed to each region. The median time between request and response is shown.

The global row uses a link Global External HTTPS Load Balancer to route requests to the nearest service.

Note: This site is intended to show relative latency to each region, and should not be used to determine the absolute lowest latency possible, or your own network speed or other network conditions. Results are not scientific.
