Not sure if this issue has been covered before. For the last 2 months a couple of pages I regularly look at seem to be being cached by Telstraclear far longer than any other ones. I have confirmed this as when I look at the pages on the work connection (telecom) the updated content is visible. Most interestingly, if I switch my routers DNS addresses to the OpenDNS servers then the updated content is immediately available on the home connection.

Any ideas why this may be happening, and will there be any significant problem in just keeping using the OpenDNS servers instead?

Pages that I know have the problem are www.macrumors.com and www.daringfireball.net

P.S. Cable connection in Christchurch

dude, OpenDNS are spammers! the only thing they actually do other than basic DNS is reply fake A records for domains that dont exist to deliver their advertisments. I wouldn't use their servers with a 10 foot pole.

you could try the (real) open root server network. http://orsn.net but you need a local caching DNS like BIND to use it.

some ISPs are known for doing this btw. have you tried their helldesk?

additionally, my first thought is not DNS, but browser cache or transparent HTTP proxy at fault.

This is still happening. It is definitely to do with who I do the DNS lookup with,

MacRumors today with telstraclear DNS

Headline is "Apple asking developer feedback on Leopard..."

MacRumors with OpenDNS lookup

Headline is "International Apple Stores : Canada, UK, Australia

If someone on Telstra Cable sees this post, could they please check Macrumors and see which page they get?

Any feasible thoughts?, not a local caching problem...

Cheers

I am on Telstraclear, and I have no problems with this webpage, or with anyothers for that matter.

What are the DNS servers that you are using?

Also what webbrowser are you using?

I'm seeing "International Apple Stores : Canada, UK, Australia" using ORSN and local caching (BIND) DNS or using Telstra Clear's DNS.

do Telstra Clear perform transparent HTTP proxying?
