Internet Effects of Last Week’s DNS Patching

We got curious to see if there was an effect from the Internet scale DNS patching going on. Our Internet statistics system suggests … no.

Internet-wide DNS traffic, 1 week

Those spikes? We are pretty sure those are massive DNS attacks.

In short, we’re not seeing a significant change in DNS traffic from before the patching to after the patching (ie as resolvers reprime their caches post restart).

UPDATE July 15 I should note where this data comes from. We’re working with more than 60 tier-1 backbone ISPs who are active participants in sharing aggregate, flow-level summaries of traffic around the world to build Internet-wide visibility into attacks and backbone traffic. This traffic is all inter-domain traffic, crossing ISP peering points. Many thanks to the engineering team who put this view together.

I’m a bit curious what the difference is and why? I have no hidden agenda. I’m just very curious about the difference.
