[AusNOG] Is there anyone from Telstra available who works in the Telstra DNS dept available?

[Chris Scholfield]

Thanks for your help everyone,  pointing to 8.8.8.8 does resolve the problem
we had.

I may leave it on that permanently now. Give TID DNS the flick since
everybody on list is saying that they are too slow in updating their
records.

 

However, I've read about people experiencing problems using Google DNS
instead of a local DNS, in regards to stuff like DNS location redirection.  

 

Considering that's the problem that we had this morning was IP location
blocking on websites we need to use, do the benefits of using Google DNS
outweigh the problems (if there are problems at all)?

 

Thanks for your help and input

 

Chris.

Hey,

 

As an FYI, Telstra's DNS is notoriously slow when updating. I recently
conducted a change for a customer we moved from dual ADSL to Single SHDSL
and updated the DNS entries.


Telstra was the last to update despite having the TTL dropped as low as it
could could go. This because the root TLDN server within Telstra only
updates EVERY 24HRS and no sooner/later. Telstra ignore TTLs.

 

So until it's passed 24hrs, you won't see downstream DNS within Telstra
updating. As someone recommended, alter your DNS pointers to 8.8.8.8 or
another DNS server until the serial on the DNS at Telstra increments.

 

Cheers

Hello,

 

We've been experiencing a problem with our net traffic.  We use Symantec
Messagelabs as our net proxy, and over the weekend they had a problem with
the AUS proxy server, and cut over to the US one.  

 

Messagelabs told me this morning that this has been resolved, but the
Telstra DNS seems to be still pointing to the states when we try to resolve
the Aus proxy address.

 

Is anyone from Telstra available in this area who can look into this please?
If you need any information, please contact me off-list.
