Website of Virtual University Of Pakistan

Has anyone able to access Virtual University website : http://www.vu.edu.pk or http://vulms.vu.edu.pk

Because every time, I am getting message like unable to find server. All other internet websites are accessable. I am using PTCL net. It was ok and accessable two days before but not now!!!

EDIT: Now the website is working n accessable. Please moderators, close this thread.
