Nervous ISPs replace Chrome as strange consumers of DNS resources

Some network operators like to wear belts and suspenders to keep their services up.
The short version
- Given Chrome’s enormous prevalence, that traffic was unwelcome.
- ICANN, plus other internetworking and governance stakeholders, told Google to sort it out.
- Durand said the Chocolate Factory gradually did.
What happened
ICANN has kept measuring the impact Chrome makes and Durand shared the graph below which shows the browser’s share of DNS root server traffic falling from 45 percent to one percent today. ICANN has now detected a new source of odd DNS traffic: ISPs that use multiple DNS servers for every one of their customers’ requests.
Why it matters
“Every single DNS query is sent three times: to Google, to Cloudflare, and to another DNS resolver,” Durand said, labelling this practice a “belt and suspenders” approach because a single resolver usually suffices to keep services up.
