Unable to get a particular web site address

[#1]

Would be obliged if any one out there could advise me on why I am unable to get the following web site address. I am told The web address is working.
wdbus.co.uk
I get Internet explorer can not display the web page
I used to be able to obtain it. I have a BT Voyager 2100 ADSL Router
It is not my computer or Norton as I am also unable to get to it through my Iphone when using my plus net broadband from home.
any ideas would be appreciated.

No problems here - are you putting  www. ; in front of it.

[#3]

Works fine here as well

[#4]

same as me, it wouldnt work without the www but this did http://www.wdbus.co.uk/

[#5]

yes done all that
it must be something to do with my router but i do not know what
as I have just tried on Safari on my iphone and get smae result.

I think there is a problem somewhere http://downforeveryoneorjustme.com/www.wdbus.co.uk/

I would run  tracert  to see if there is sever packet loss

My Router had change the mtu to 1400 from 1500
re set it to 1500 and now able to get the website.

A few years ago I had a problem with one website which I coud never access through plus net.
I reported it to plusnet, they looked at it and said there was a problem with the way the sites DNS was configured.
That may be so, but why was I able to access the site from every other network other than plusnet.
