Well I mean if you have an external endpoint where users/customers are reporting packet loss or connectivity issues and you have determined that your actual endpoint is not having issues for example, and you believe it to be a network issue somewhere along a route, then you can run this tool from various geolocations in the drop-down. I also like https://mtr.ping.pe/ which runs from a bunch of locations simultaneously
Makes sense to me. Its like a free manual alternative to Thousand Eyes. I like the layout and responsiveness of the site. I especially like the compact view.
Is the plan to keep the site free? All the sites like this I have used throughout the years ultimately end up pay-walled or highly rate limited.
