What developers can do
- Retry with backoff: configure exponential backoff at the SDK layer so short blips self-heal;
- Dual backends: keep a fallback model on critical paths — see the alternatives check-in;
- Watch the status page: it supports update subscriptions.
It is the largest publicly visible outage within V4.1-Flash's five weeks on the market; for ongoing stability notes see the five-week review, and for cost context the API pricing explainer.
