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

martinveasey — Tue, 22 Mar 2022 14:15:33 GMT

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 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * * 12 * * *

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

No problem accessing the website here.

Here you go (sorry about the formatting):

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?

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

Chris

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.
