There must be or have been issues at the Singapore serve. I experience frequent disconnection, and when connected, I frequently get the This page can’t be displayed error message. Often the issue persists for more than 1 hour at a time. There is nothing wrong with my own internet connection; this is because as soon as I disconnect SecureLine, the problem goes away.
This is only my 3rd week into my yearly SecureLine subscription, and Singapore is the only server I get to pick due to geographic considerations therefore ping responses. So far, I am far from impressed.
