Help with non loading websites

Ok, this isnt a problem with ZC and not a problem with my host , but going to a website say pipercross-airfilters.co.uk all i get is a message saying website cannot be displayed, after a number of tries and clearing the cache etc but without success. However the website works when being accessed through my phone using my mobile providers internet. Does anyone know of a reason why my site wont load through my pc or why the broadband is blocking it but it works fine through a mobile phone.

Thanks

You didn't say whether you could access other sites on that computer. Generally when that happens your internet connection is not working on the PC and you're able to access the site from your phone because that network connection is up. I'd try powering down the network equip (modem, router, PC) and see if that fixes the problem.

Site loads fine for me. I guess you've resolved this issue?

No i still have the issue, restarted pc, rebooted the modem. Done a system restore to yesterday when everything was working fine. The pc im on now with broadband everything seems to be ok, all sites i have checked are all loading as usual, the website that belongs to my host is all working fine, i can log into my account to the server fine, but as soon as i click on my admin which then loads up on my domain i get the error problem. Really strange. Oh and if i use my phone to access wifi to the broadband it also fails to work, so the probelm is with the router/internet somewhere

Thanks for your time
