[AusNOG] DNS problems resolving sync.deakin.edu.au

[John Mann]

Hi,

Deakin University recently dual-stacked their Akamai cache for
sync.deakin.edu.au .

Since them, some students using a couple of ISPs can't resolve the DNS name.
For example:
---
> nslookup sync.deakin.edu.au
Server:  belong.gateway
Address:  10.0.0.138

*** belong.gateway can't find sync.deakin.edu.au: Non-existent domain
---
"blogs.deakin.edu.au" is setup similarly to "sync.deakin.edu.au" but that
does work.

If the user changes their DNS server to 8.8.8.8 or 1.1.1.1 then they do get
through.

Problematic ISPs include:
   Belong
   Aussie Broadband
   ...
I've tried the frontline technical support numbers, but didn't make much
headway.

Does anyone know how/why this DNS problems would be happening?

Can some technical support people from ABB and Belong please contact me?

Thanks,
     John Mann
