Cannot access a Cloudflare proxied (US) website via TalkTalk ISP

[martinveasey]

Hi - I'm trying to access www.sculpturescript.com on both of my two TalkTalk accounts but only getting timeouts.

The website is proxied by Cloudflare so, despite being hosted in the UK, a DNS search lists the target IP address as 162.159.137.85, which is based out of San Francisco. I know the website is legitimate, as I own it.

Looking at traceroute output indicates that the routing isn't even leaving the TalkTalk system:

traceroute -m 12 162.159.137.85
traceroute to 162.159.137.85 (162.159.137.85), 12 hops max
1 10.231.0.1 0.584ms 0.452ms 0.438ms
2 * * *
3 78.144.8.122 10.229ms 9.884ms 9.915ms

5 * * *
6 * * *
7 * * *
8 * * *
9 * * *
10 * * *

Could it be that TalkTalk is blocking the traffic? Can others here perhaps access the website via TalkTalk?

Morning,

Thanks for the update 🙂

Thanks

Thanks to those who responded.

Turning the router off for an hour proved the charm, TalkTalk assigned me a new IP address and all is back to normal. If only I know why this made a difference ...

For completeness, I also use Google as a DNS resolver.

Hi martinveasey,

Can you switch your router off for 30 minutes then switch back on and retest - please let us know how you get on

I have just clicked on that link and the site came up straightaway. Mind you, I am using non-TalkTalk DNS servers, so I don't know if that makes a difference?

No problem accessing the website here.

Here you go (sorry about the formatting):
