So while right now not having IPv4 connectivity is unlikely, it does happen and will only become more common. People are also introducing monstrosities like carrier-grade NAT to delay the inevitable, but we really should not encourage that madness and just add IPv6. It generally is very easy to do.

I saw that and was very disappointed by Fastly. It means I won't consider using them for anything I do at this point in time.

Is the PSF willing to ask push Fastly a little bit on this, so we at least have timeframe?

It’s very viable right now I’ld say. If I remember correctly Cloudflare has a free service where they add an IPv4 frontend for IPv6-only servers so you can still provide service to IPv4-only users.

Wichert.
