We were trying it out for quite some time and it worked well apart from two things: anonymous access and the bigger blocker for us was AGPL. Minio and Garage having the same license means I would always prefer Minio.
A CDN makes a lot of sense to me, having static assets that get cached close to users is a brilliant way to speed up requests. As the article points out, this is a very hard problem to solve for anything that touches a database or is not static/cached content. This is also why I don't believe in the idea that Fly.io pitches. Additionally you have the legal things to take care of with GDPR, etc. so a local database is probably the way to go for most projects.
There are certain auction platforms, I sold my IPs through https://auctions.ipv4.global/ which went smoothly. The registries have waiting lists for resources that get handed back to them (very rare). You need to be a member to buy IP space though.
This is bad, but storage boxes are already a backup target and the content of the backup target (actual files stored in in box) are not affected... "only" snapshots.
Hetzner has a great price/performance ratio, but they are not rock-solid. Speaking of the private network... look at their forum where people complain about downtimes for their "vSwitch" every other week, sometimes it doesn't show up on the status page because it happens on the weekend (lol).
Sorry but they announced something, hyped users (including me) and didn't deliver (yet). I understand this is a lot of work and it's free software, but it still doesn't feel right and has nothing to do with being senior UX designers. They already announced and showcased a very good looking version of Thunderbird.
