I thought fallback was a nice-to-have until OpenAI billing issues broke 3 agent runs in one week

The author of this article learned the hard way that having a fallback system isn't just a nice-to-have but a necessity for reliable operations. During a week plagued by unexpected OpenAI billing issues, three agent runs were interrupted, highlighting how critical robust fallback mechanisms are for maintaining service continuity. This incident underscores the importance of not just adding fallbacks as an afterthought but ensuring they're integral to the system design, especially for 24/7 operations.
