Yeah, that's not true in my experience, and I'm a very happy Hetzner customer and been using them for years, they are a step below in reliability, no matter how much I love them it's hard not to see that.
I've used Vultr for about the same amount of time, and I never got an email that some network switch had a hardware failure and it'll take a couple of hours to restore connectivity, but I've had that happen with Hetzner more than once, in the same time-span. And again, I say this as a Hetzner-lover, and someone who prefers Hetzner over Vultry any day of the week.
