Facing high ping issues in Asia amazon Ec2 and amazon lightsail from the past 3 days.
Kindly resolve the issue. Please
Are you using mudfish app for android only? I want to check the ping information between your phone and mudfish nodes but not available to see. 
So due to lack of information, it’s not easy to analyze your issue.
However let me check these nodes you mentioned and update if I found something.
