Path of Exile Ping Tester allows you to ping each and every PoE server and measure the latency. The status column shows when the pinging was started and completed. This tool is very useful for measuring your actual ping before joining the game, because it will allow you to find the best server for your location.
PoE Server Status Checker can find the reachability and status of Path of Exile servers. From the IP Address: column, you can find which IP belongs to which server. Each server has an indicator showing its reachability. It can be used to quickly find out whether servers are online or offline.
