[AusNOG] Google DNS 8.8.8.8

Wed Apr 20 16:49:03 EST 2011

We were having the same issue at a customers place. www.news.com.au<http://www.news.com.au> was really slow. I think it has something to do with some load balancing providers like akamai.net. When you use the Google dns servers they think your in the US and give you as US mirror instead of a AUS mirror.
I did a few tests and the after changing the DNS servers to the local ISP and clearing the DNS cache I got a ip from akamai.net that was local to Australia and a lot faster.

Thank you

I remember distinctively that unlike google.com<http://google.com/> which has an Australian mirror (and resolves back to AUS through some routing black magic), their free DNS resolvers don't which was the reason why I didn't want to use them.

But I could be remembering wrong... :)

Hi all,

Just thought I'd share something I discovered today that might affect some of you.  Recently at home I've been having weird international speed issues (ISP is Internode) but only to certain locations. Speedtests and line sync were fine, some downloads great, others crawled.  Vimeo was unusably slow, the App store was barely usable.  Internode reported no issues.  Swapped routers, no change.

I finally nailed it down today - in a stroke of laziness I'd set 8.8.8.8 for the DHCP pool's DNS server.  Turns out, 8.8.8.8 doesn't seem to exist in Australia anymore.  I swear this used to be in Sydney, it was around 60ms away.  Wasn't it?  Now, from my home, every box I've got around Au and every Traceroute site I can find, it's showing up in California.

A geolocation of the last hop before it finds its target: http://www.ip2location.com/209.85.241.154 - defs in the US.  So Google's anycast DNS from the US is returning US-local mirror addresses for things instead of using Au CDNs.  And it's causing weird, per-destination slowness.  So that's the reason my 'net has been sporadically terrible this month.

Anyone else got anything from 8.8.8.8 in Australia?
