[AusNOG] DNS stuff-up

Wed Feb 12 16:27:46 EST 2014

I believe Telstra had a C7 platform issue earlier this afternoon (around 3pm). Impacted some of our mobile traffic. I understand that Telstra rolled back the changes to correct the problem. DNS impact ?

We just had a strange DNS issue which seems like some parts of the internet lost reachability to our DNS servers. 

Suspect its part of a major Telstra outage, as people reported outages on bigpond, ISDN onramps, and mobile calling.
