Firefox, you know you tapped Cloudflare for DNS-over-HTTPS?

On January 23 this year, ISC received a report of a breakdown with .net domains. When it investigated, it discovered crucial A and AAAA records, which glue .net domain names to their IPv4 and IPv6 network addresses, were missing.
ISC quickly figured out – within five minutes, according to its timeline – that the issue lay with internet nodes it operates in partnership with Cloudflare, and escalated the issue to the web infrastructure business.
As one veteran internet engineer, Bill Woodcock, noted on Twitter: “What happens when critical functions of the public Internet are co-opted for private benefit? Transparency and accountability are lost, infrastructural spending cut, things break.”
With core elements, like DNS, you need systems as independant and numerous as possible to avoid a central control. Mozilla in bed with Cloudflare is doing exact the opposite.
