Well yes considering the downtime they had. SLA is just words on a paper, you also need to not fuck your infrastructure up. Even if all self-hosters had 99% uptime which is bad, it's easy building a system that replicates data on a few of them to achieve resiliency. People need to stop assuming they can be 100% reliant on a single host and actually design their systems to take downtimes into account and recover from them
