Re: [nznog] TelstraVodaHug core lag

16 Sep 2013

      You lot sure its not just being served from the USA rather than domestically or Sydney. If so I don't think there is any real problem with this. Not an optimised route sure, but that's Telstra/voda/hug's prerogative.  

If your using it for DNS resolution (its intended purpose), don't. Due to the anycast nature of 8.8.8.8 using it will break most regional CDN's and stuff like your Akamai will end up being served from somewhere close by like Singapore. 

Is there any real impact to your service, or have you just noticed "an interesting change in routing"?

Hi all
Breaking with recent tradition and discussing something related to the operation of the NZ tubes...
My employer has a TVH business fibre connection, and since around midnight Saturday/Sunday the latency to 8.8.8.8 (one of my Smokeping test subjects) has been consistently > 160ms.
mtr tells me:

The sudden latency jump at akl-grafton-core1.ihug.net kinda leaps out. Is anyone else seeing this? And is this something that the TVH admins are aware of? Please don't make me deal with helpdesk!
Cheers
