ChatGPT is down! How is your startup product doing?

So it looks like today one of those rare days when OpenAI ChatGPT downtime. I've noticed something interesting - many of my favorite AI tools that use OpenAI under the hood are still operating. This makes me think that the APIs might still be working, even though some services are down. It got me thinking: What gameplan have you all put in place for your products that heavily rely on OpenAI's APIs? How do you handle situations when the API becomes unavailable? I'm curious to hear about your strategies, especially from those who've dealt with previous outages.
