Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have the website *.co.uk but havn't been able to access it recently. I know its live, I can access it using vtunnel proxy server.

I'm having the problem just on my virgin (uk) internet connection - I've tried their tech support but its useless... I need to work out where the point of failure is so I can proceed.

I have the following when attempting a tracert:

C:\Users\Josh>tracert ***.co.uk

Tracing route to ***.co.uk [109.70.148.169]
over a maximum of 30 hops:

 11     *     ^C
C:\Users\Josh>

Virgin have said they can't do anything other than notify the owner of the server, and also told me other virgin customers are probably experiencing the same issue.

I've tried to do an IP lookup on 217.146.94.6, but it failed. IP lookup on 212.250.14.18 told me there was a dns issue.

I'm not sure how I can correct this issue. Does anyone have any ideas?

Thanks!

There is nothing wrong with this traceroute.

What you are seing is 217.146.94.6 is blocking ICMP probes traceroute uses.

I've made traceroute myself but not with ICMP packets, but with TCP

# tcptraceroute 109.70.148.169

The fact that 217.146.94.6 has no DNS entry has absolutely no effect on connectivity past that hop.

can you give us some other info like

telnet 109.70.148.169 80, or what ever you are seeing as 'not working'

edit: you can also show your provider that ton of hosts around the world can normally access your website, and there is no reason for you not to be able to do the same

+1 for doing the trace with TCP packets rather than ICMP -- good troubleshooting step to provide more info to Virgin & Killercreation –  voretaq7 Feb 17 '11 at 20:03
    
Tried to telnet, but putty (I'm on Windows) died after about 10 seconds of not doing much. When I try to access the site I get "The server at unifancydress.co.uk is taking too long to respond." from Firefox. Thanks for the info though, I'll get onto Virgin and KillerCreation in the morning with this info. Didn't know about the different icmp/tcp traceroutes, only have a fairly limited knowledge in this area! –  Josh Feb 17 '11 at 20:21

do you use any firewall on your machine? just in case can you try turning all firewalllike apps off and try again. –  Hrvoje Špoljar Feb 17 '11 at 20:23
    
@Hrvoje, annoyingly its the same with any machine on this network. Even with an iPhone using Wifi. –  Josh Feb 17 '11 at 20:25
    
then ask your hosting provider (one that owns the server) If they have any local firewall blocking access from your ISP provider, or your IP. Tell them 'everyone' but you can connect to the page and you/I are running out of ideas :/ –  Hrvoje Špoljar Feb 17 '11 at 20:32

The traceroute tells you that ICMP Echo (ping) requests stopped being returned after the host at 217.146.94.6 (Killercreation Networks Ltd, who appear to be hosting your site as well).

If you are unable to view your site (and can't connect to it on port 80) your beef here is between Virgin and Killercreation Networks, and you should probably speak to both ends of this particular snake to try to get the issue resolved (You're a paying customer of both services - your voice should hopefully carry some weight).
The list of things that can cause a site to be unreachable from a specific provider is literally a mile long, and the fastest way to resolve it would be to get the networking folks from both ends to talk to each other.

You may also want to point Virgin at the results of http://www.downforeveryoneorjustme.com/unifancydress.co.uk (which proves that from their servers' vantage point your website is working fine -- and I can confirm it works for me from NY/US, so IMHO you're right to point at Virgin and say they're the problem here...

Hi, thanks for the info, I did mention downforeveryoneorjustme to them, and they could access the site fine in the office, though they explained they'll be using a business solution rather than residential internet. I'll get onto both Virgin and Killercreation in the morning with this, hopefully get it sorted! –  Josh Feb 17 '11 at 20:26
