You people call 99% uptime "unacceptable" then give three stars. Three stars means average. Average means it works. If your site is down six hours a year that is a YOU problem for not using a CDN. I have been on Contabo five dollar plan for two years. Zero tickets opened. Zero. Because I read the docs before clicking deploy -- https://docs.docker.com
Every "downtime" thread here is someone who did not configure their firewall or tried to run Docker on 512MB. Stop normalizing incompetence.
RTFM
