Looks like 'ping' has been turned off on the server you're trying to reach.  That is fairly common practice.  Are you aware that 'riskspectrum.com' doesn't have a web site?  That it is redirected to 'http://www.scandpower.com/en/risk/'?

The reason the first lookup failed is because you put four "w"'s .  The reason you don't get a ping reply is as DaveBaldwin said, ICMP reply is disabled- either at the server or at their firewall.

This is very common practice and not indicative of any problems typically.

hmm...I see but why is it failing in tracert too? I mean is it again disabled too?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

 
Bill_FleuryCommented:
tracert uses ICMP packets as well, so in this case, the hops that respond still reply to ICMP, but once it starts timing out you've come across a router or host that drops ICMP traffic.

Here's more info on why ICMP is disabled in some cases:

Thank you. One final thing, when I try for the address as attached, why isn't it replying?

Bill_FleuryCommented:
It doesn't reply because they're dropping ICMP, the same as the other site.  The riskspectrum link off of it does work though, attaching screenshot. Screenshot

One more thing, www.riskspectrum.com redirects your browser to http://www.scandpower.com/en/risk/

Dave BaldwinFixer of ProblemsCommented:
In your browser it will redirect to 'http://www.scandpower.com/en/risk/'.  So 'http://www.riskspectrum.com/' is not a real web site but a redirected domain name.  Which means that it may not actually represent a server that can respond to anything else.

Bill_FleuryCommented:
If you're wanting to check your ability to communicate with the server doing the redirection you could always telnet to port 80 and see if it opens a connection to it or not.  At a command prompt, type telnet www.riskspectrum.com 80

It should give you just a flashing cursor, hit enter a few times and it should show you some http header stuff.

I seem to connect via telnet <addr.> 80 but I couldn't see anything when I press <enter> multiple times.

Bill_FleuryCommented:
yeah, not 100% sure it could depend on other factors- don't have telnet on this machine and don't really want to install it (borrowing gf's laptop to reply to you).   Sounds like everything's working the way it should though- not sure why you're not getting redirected when you go to that URL in your browser.

This is what I get with GRC's Idserve.  I think to get a response via telnet you would have to send an HTTP request that the server could respond to.
Looking up the domain name for IP: 195.198.227.249
The domain name for the IP address is: www.riskspectrum.com
Connecting to the server on standard HTTP port: 80
[Connected]  Requesting the server's default page.
The server returned the following response headers:
HTTP/1.1 302 Redirect
Content-Length: 153
Content-Type: text/html
Location: http://www.scandpower.com/risk
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
Date: Wed, 01 Dec 2010 03:53:42 GMT

Could you give me an example for HTTP requests?

Kind regards.

"GET / HTTP/1.0"

Here's a page with instructions for using telnet like you are: http://www.jmarshall.com/easy/http/http_footnotes.html#manually
