On the Fireside Fedi interview with Jerry ( the admin of Infosec.Exchange Mastodon instance ) a scary truth was suddenly revealed ( on 34:11 ): Just to keep the instance up and running he needs to spend up to $5000 a month, pretty much out of his pocket. Donations to the instance barely cover any of that. And if he will ask people to pay to use it, they will, rightfully so, switch to a different instance.
Storage. In the video he says that backups alone costs $500/month.
Also, given that the instance is called “infosec.exchange”, you can be sure that he is not running this on some cheap VPS.
Maybe the problem is that they are using ridiculously overpriced enterprise services like AWS or Azure, which provide their own solutions for a lot of common things like backups, replicas, logging, etc, but cost 100x more than what you can get with DIY on some cheap VPS if you’re fine with spending 1.25x more time.
Why not, though.
