[public-dns-discuss] Route from australia to 8.8.8.8 is broken



Hello,
Approximately since 2018-10-05 I noticed that latency of 8.8.8.8 responses got significantly slower. I tested the route and got following output:

C:\temp>tracert -d 8.8.4.4

Tracing route to 8.8.4.4 over a maximum of 30 hops

You can see that 8.8.4.4 seems fine. However 8.8.8.8 is acting weird - after it gets to AS15169 (google's network) it hops many times and instead of typical 26-30ms it takes 100ms more.
I tested this on multiple ISPs in Australia and it is happening everywhere.
I dont think anyone except google could possibly affect routing within AS15169, therefore I believe you guys should be aware of this situation so you can fix it.

Thanks for any reply
