Yes, we have raised a ticket upstream. Simply trying to ascertain if it's just us that are affected or if there is potentially a wider issue.

Have you lodged a fault with APP/TPG?

If there is a fault, only they can fix it, so it's best to talk to them first.

Hello all,

We are seeing some unusual behaviour with a TPG/AAPT service, where traffic destined for Quad9 DNS is being routed to their PoP in Singapore via Level 3. According to Quad9's status page, there are no faults with the Sydney PoP.

Is anyone else seeing similar behaviour?

Regards,
Christopher H.
