its always DNS
It's Not DNS
There's no way it's DNS
It was DNS
Except when it's BGP.
Which is just DNS with extra steps
That is... not how bgp works my guy
Except when it's a trunking failure before BGP
BGP was that major facebook outage a while ago. But your both right, for big things like that... Its always one of those two.
