One example from my own experience is with DNS. Back in 2015 we had a series of outages due to the provider who was hosting our DNS zones.
First the provider had a six hour outage during which we could do nothing, and we couldn't even get in touch with the provider.
Then we tried redundancy across two different DNS providers, which lead to another two outages when the first provider did not handle redundant setups correctly.
At that point I said we will never want to go through this again. And we decided to operate our own DNS servers with redundancy across four different hosting providers.
We have now used that setup for over nine years and not had a single outage of our DNS zone. We have of course had individual DNS servers be down for some time every now and then, but we never had all four go down.
Such a track record of course helps when I am making arguments for multi provider redundancy. I can point at this setup and say over nine years with 100% uptime, had we used Cloudflare we wouldn't have had such a high uptime.
