DNS Flag Day and freebsd.org problems

[David Magda]

Hello,

On February 1, 2019, there will be some major changes to DNS with regards to EDNS:

> A number of DNS software and service providers have announced that we will all cease implementing DNS resolver workarounds to accommodate DNS authoritative systems that don’t follow the EDNS protocol. Each vendor has pledged to roll out this change in some version of their software by the ‘Flag Day.’ 
[…] 
> Domains served by DNS servers that are not compliant with the standard will not function reliably after February 1, 2019, and may become unavailable.
> 
> If your company’s DNS zones are served by non-compliant servers, your online presence will slowly degrade or disappear as ISPs and other organizations update their resolvers. When you update your own internal DNS resolvers to versions that don’t implement workarounds, some sites and email servers may become unreachable.

It turns out that freebsd.org is effected by this:

> This domain will face issues after the 2019 DNS flag day. It will work in practice, BUT clients will experience delays when accessing this domain. We recommend you request a fix from your domain administrator! You can refer them to https://dnsflagday.net/ and technical report

Who is the person that should be looking at this for FreeBSD?
