Do note, HOW they are hosting, pays into this a lot.
I have a server I host things on here locally-
256G of ram, 32 cores/64 threads. 130T of storage. Nvidia Tesla GPUs. Coral TPUs. Lots of NVMe too.
It costs 20-30$ of energy, along with internet use-costs.
Hosting, something of that scale in the cloud, would be outrageously expensive. However, here in my local home-datacenter, with redundant power, internet, and everything, its honestly not that bad.
And- I assure you, there is redundancy. My lemmy had basically no downtime AFTER getting hit by a tornado, and power to the city being out for most of the week.- > lemmyonline.com/post/3751
