I move slowly and test things in my test environment before tewting them in production.
I may not have much, and new features may be slow, but once I get it done, it's rock solid.

That isn't to say I don't make mistakes that make it to production. I do. But in most cases people just go back to the working version and everything works just fine again.
And in cases like comms servers, where it's only useful if it's on a network (preferrably the internet), I catch things pretty fast.
