AFAIK it's not like FastMail has a crazy number of network-related outages, so overall it doesn't seem that "prone to failure". As with many things, it's a trade-off with complexity and costs.
- paulryanrogers 3y agoI'd argue that often the CDN or transit isn't drop-in replaceable. So it's usually more than 2x the cost as one has to maintain two architectures (or at least abstractions). That includes the expertise and not optimizing for strengths of either, or building really robust abstractions/adapters.
