Hi,
There is an X mark in the self-diagnostics page: Master Server test: DNS Poisoning Issue
I also noticed that RTT update doesn’t work well, since the majority of the server often have a value of “-1” in the nodes page, and with auto-configuration I get higher ping than normal.
As an example, I just tried Auto Selection towards an amsterdam server, and a russian node was chosen (I’m from Italy, so it doesn’t make sense obviously)
