I'm facing a weird problem with some websites. In my network nobody is able to access a particular website, whereas that website is up when I checked it at http://www.isup.me/.
This happens quite frequently in my network. Not only this site, it happens with some other websites as well. But after a day those sites are up again in my network.
What could be the reason behind this? Is there any solution for this issue?
Update: I tried to reach website with IP address by using ping but couldn't successful. I'm using Windows operating system. I tried to access this site on all browsers (chrome, IE, firefox) Our network has a router but we dont have access to it. But I can request my administrator if anything requires to be done.
1Can you reach this website by its IP address? What is the DNS set up for your network or your computer? Have you tried changing it? Which operating system(s) is/are there on your computer(s)? Does your network have a router that you can access? – slhck – 2011-07-11T07:05:25.387
1@slhck: I've updated the question, please have a look at it. Can you explain what do you want to know about Dns setup? – JayaprakashReddy – 2011-07-11T07:11:45.547
1See what happens with traceroute (tracert in windows), as it should give you some indication of where traffic is stopping at. – Stephanie – 2011-07-11T07:42:07.533

But thanks for everyone, I would definitely use all these methods next time when any other site is down only for me. – JayaprakashReddy – 2011-07-12T07:37:55.710
I did use tracert but it stopped after 10 hops and I couldn't find out who owns the last successful IP address given in the tracert results. I'll definitely try to get into more details next time I face this issue. – JayaprakashReddy – 2011-07-12T07:39:13.760
