I am located in the Eastern United States and have been using the North American server, which I understand to be in Quebec, Canada.
About two weeks ago, my stale share rate started increasing to over 3% but never higher than 4%.
Two days ago, I switched my four rigs to connect to the EU server, and the stale rate has dropped to under 2%.
Ping times show the North American server to be closer. Any thoughts as to why I would get a lower rate?
Load on the NA server?
