At least they haven’t messed with Heroku.
Heroku, on the other hand has been a hassle-free solution for my company over the past 7 years, and short of a few outages (which were actually the fault of AWS from what I remember), it has been absolutely reliable.
We've worked hard to incorporate reliability lessons learned from building the platform at scale especially as we've grown [1], and I hope you'll give us another chance. If I can do anything else to help, my email is my HN handle at render.com.
