>> Do you build the monitor with your domain or the ISP domain?
I believe you are referring to the target resource as our domain or the ISP domain for the latency metrics.
While adding an ISP Latency monitor, we ask for the resource to which the latency should be measured from the chosen locations. Once the monitor is created, based on the check frequency configured, we constantly measure the latency between the chosen locations and the target resource. Currently we support measuring latency only from our 110+ geographical locations.
As per the screenshot, every 5 minute, we measure the latency between the locations: Seattle, Amsterdam, Chennai, New York, Sydney and the target resource: 184.108.40.206
Please let me know if you need any clarifications. I would be happy to assist you.
