Ultra Low not Working Correctly in Optus Mobile - Australia (Melbourne)

Olivier Poitrey Romain , can you please help and check the routing of Ultra Low Latency for Optus Mobile here in Melbourne, Australia? It seems it’s not working as expected?

Please see attached. When running ping.nextdns.io, it doesn’t show where I am connected.

When i am doing test.nextdns.io, it shows i am connected to Sydney, but i am here in Melbourne.

I’ve attached some photos since i cannot run diag in my iphone 11 pro.

Also, is there an issue with anycast 2? It’s going to zepto-lax which is Los Angeles? Isn’t that too far away from Australia?
 

thanks in advance for the help! xx

    Olivier Poitrey Romain Cointepas , any updates on this? Do i need to provide anything else? This seems to be a routing or logic issue. I’m here to report to make the app better. ✌🏻✌🏻
    i think we need to fix the ULL routing for Melbourne and Anycast 2 ( should go anywhere in Australia instead of Zepto-Lax ). This only happens on mobile LTE - Optus Mobile.

    Which version of iOS are you using and what is the version of the NextDNS app?

      Olivier Poitrey i’m using the latest ios version 14.4 and using the latest NextDNS for ios 2.0.1.

      Olivier Poitrey there is a new ios version 14.4.1 and the issue is still there so I don’t think its the ios version.

      this is probanly hard to fix since we cant really do diag using an iphone. We can only provide screenshots.

      I just tried it again (ULL enabled) and i am connected to hefised-sao. This is the result of test.nextdns.io. In the ping.nextdns.io, it’s not showing which connection i am connected. hefised-sao is anycast2 at 523ms. Is this even part of Australia?? 🤣🤣

      router.nextdns.io says i am zetta-mel.

      Please let me know what i need to do next. ✌🏻✌🏻✌🏻

      Lady Arwen please download a traceroute app on the app store and traceroute : anycast.dns1.nextdns and anycast.dns2.nextdns.io.

    Olivier Poitrey any updates on this? ULL seems to still not working correctly in mobile here in Melbourne. The test.nextdns.io is showing different from ping.nextdns.io.

    also Anycast 2 is still being routed to Zepto-Lax which is not Australia?

      Olivier Poitrey yes. The only thing that change is the resolver. It changes from 21 to 22 (mostly stays in 21) But server  stays with gsl-melb.

      Olivier Poitrey my friends also has this issue where the ULL seems to be behaving weirdly using mobile - Optus here in Melbourne. It seems that the steering logic is not matching it correctly to the nearest and ULL faster servers... even Anycast 2 is weirdly map to Zepto-Lax which is Los Angeles?

    • olivier
    • 3 yrs ago

    Seems like Optus have their DNS infra all centralized near Sydney for the whole country. This prevents ultralow from doing a better job for Optus customers far from Syd. This must cause the same issue for most CDNs like Akamai, who use the same steering technique.

    They could fix that by enabling ECS in their resolver, or by adding more DNS PoPs in AU. We will contact them in that regard.
