[AusNOG] Google DNS 8.8.8.8

[Angelo Giuffrida]

>From what I remember, 8.8.8.8 never used to resolve back to Australia.

I remember distinctively that unlike 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?
