GMX Mail not accessible on PTCL DSL

I am unable to access GMX Mail's website [gmx.com] for the last few days on PTCL DSL. Don't know about other internet providers, but gmx.com is accessible through my mobile phone. Are there any gmx.com users on this forum who are experiencing the same?

It works on Zong's LTE.

Try changing your DNS settings to another server, then check. Otherwise, the link could be temporarily down.

shaheerk, thank you. I am sure that you are right about the problem (and its solution). However, brefore I could have changed the DNS settings, the website has become accesible through PTCL DSL.
