Um teste rápido no navegador é oferecido pelos Relatórios DSL
Aqui está a descrição deles para o teste:
Test how well your connection can reach a globally distributed set of servers. All servers are pinged twice a second (50 probes a second). The best and the current average difference from best latency is displayed. Every 30 seconds, the quality of the connection is graded from A+ to F. Any servers that are unreachable are highlighted.
If there is local congestion or ISP problems then you may see volatile latency numbers and the radar graph will show an inner green area and an outer green boundary. A stable connection will show stable numbers, a good grade, and the radar graph will be a solid color with very little movement and activity.
