Such high packet loss implies some type of problem in the Internet between you and the server. It's strange that you all would be experiencing issues from so many different locations around the world, but I can't replicate any routing problems to the server in my testing and all bandwidth metrics look normal. Even doing reverse ping tests from the servers to your IPs returns normal results.
You could try contacting your ISP, or wait until later next week to see if these problems resolve themself. Perhaps all of you are passing through some router or network link that's having issues.
