[AusNOG] Google DNS

Tue Oct 14 08:48:20 EST 2014

Ahhh, that'd explain why the internet at home was sluggish this morning :-p

Using google DNS there, as it's more reliable than TID's supplied DNS
servers :(  There've been four day-long outages of uneeda in the 10 months
since our TID DSL was finally turned on)

On the upside, this pointed out to me that I need to test more than just
connectivity to 8.8.8.8 through each upstream, to decide whether their BGP
feed should be enabled or disabled.. ;)

 We ran to the sounds of thunder.
We danced among the lightning bolts,
