What is the geolocation IP database used for the information at the top of the website?

DB-IP

Checking hosts

"0/4" for "Ping" check

0/4 means that all of 4 ICMP packets are lost. Usually it means that the server is down or ICMP packets are blocked by a firewall on the server's side.

Incorrect result of UDP ports checking

It's correct. If there is no UDP answer from a server it shows "Open or filtered". If there is an answer that UDP port is unreachable it shows "Connection refused".
