In addition to the traditional swiss-army knife known as "telnet", getting "curl" to dump just the HTTP headers is also a handy one to keep up your sleeve:
0:>curl -I http://triplezero.com.au
HTTP/1.1 200 OK
Connection: close
Date: Tue, 09 Feb 2016 04:45:18 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET<http://ASP.NET>
Content-Type: text/html; charset=UTF-8

Also telnet wont work with SSL sites (ie, https), but if you have openssl installed, you can do this instead:
0:>openssl s_client -quiet -connect www.google.com:443<http://www.google.com:443>

The openssl method also works on other SSL-enabled service like POP3S and IMAPS etc. I have it aliased in my shell config:
alias stelnet="openssl s_client -quiet -connect"

...then all I need to do is: "stelnet host:port"

Just good to have tucked away in case you need to break out the command-line hammer.

Cheers,

James

Traceroute is only one tool in a toolbox, and frequently not as helpful as you might hope.

Yes, it appear to not be reachable....

However using another tool  it clearly IS working....

# telnet triplezero.gov.au<http://triplezero.gov.au> 80
Trying 2403:d500::48...
telnet: connect to address 2403:d500::48: No route to host
Trying 115.178.104.72...
Connected to triplezero.gov.au<http://triplezero.gov.au>.
Escape character is '^]'.
GET / http/1.0

HTTP/1.1 403 Forbidden

There's also a hint there....
