Problem Accessing site

[fez]

Hi Guys, really weird problem here that is doing my nut at the moment. I have built a site for someone and had it on a test subdomain of my personal site for showing the client before it went live.

It went live yesterday on another server and was all fine, everything worked ok. Came back to it today and I couldnt visit the site. Was rather worried but emailed the other guys involved in the build and they can see it fine. If I use my mobile to view it via my wi-fi it wont work but if I go onto 3g then its fine.

I have tried clearing the DNS cache, looked on the server for any blocked IP and there is nothing suspect. I can only access the server cpanel via a proxy which is what I did to investigate. I can't access the ftp either so its something to do with my IP I imaging.

If anyone could help I would love them forever.

Reboot your router?

Tried that mate, I am going to force it to change IP and see if that does anything.

I think that I might have found the problem. Apparently if you leave a few web browsers open on the same page at the same time all coming from the same IP then the server will block you. So when I was testing it for compatibility it caused the problem.

If I can change the mac address of my airport extreme it should be ok, only issue is that I cannot find a way to do that now.
