Same for me, ssh access was intermittent, but at least I have reliable local builds when GitHub actions is out but access works. With AI running Jenkins is not that hard. I build large cuda containers so cost alone ruled out hosted builds for my usecase. There's a bit of update churn but nothing broke so far. I ran around 2000 builds last year. I run it on epyc 7v12 128gb ddr4 host.
