I've been using Netlify for several sites for the past year or two. According to my uptime monitoring, they have 1-5 minute outages about once a month. It seems like it's always been like this to me.
I've been considering moving to Cloudflare pages as I'm heavily using Cloudflare for other things, but I haven't looked into it yet.
I use Netlify for deployments but I put it behind a CloudFlare CDN rather than use the Netlify's CDN. I didn't do that for any specific reason than I was already using CloudFlare and seemed to make sense to use it for what they're good at. I haven't noticed any outages but don't have any high-traffic uses that would notice 15-minute outages.
We tried this but found that while Cloudflare pages is great for something simple, they're missing a lot of features that make it truly business production ready. For instance, we use a monorepo, which Cloudflare pages doesn't support.
That's about what I was expecting. I was expecting Cloudflare pages to be pretty basic. It's just a feature owned by a team compared to Netlify's entire business.
Maybe I'll just get enable the Cloudflare proxy for my Netlify sites.
