An AX161 at Hetzner with 32 physical cores (EPYC 7502P, 64 threads) costs ~$130 per month, that works out to $0.17/hr ($0.0053 per core per hour).
8 dedicated 64t/128gb servers for 2 years, 0 cumulative seconds of downtime, perfect record.
There's something to be said about companies where things work so you don't need support. Some companies make you go through support for IPMI, and sometimes it's self-service and you only need to go through self-service if it breaks.
That being said, Hetzner sometimes has weeks where there's no setup fee on some of their servers. Doesn't seem to be the case for these ones at the moment though.
