DeepSeek says it has found cause of server outage, fix underway

For an AI developer whose models have become a reference point in open-weight and low-cost inference, an outage that reaches both the consumer chat surface and an API tier is a reminder that competitive positioning increasingly rests on reliability, not just benchmark results. The affected API matters most: developers who route production traffic through it absorb the downtime directly, and repeated incidents tend to accelerate multi-provider fallback strategies. Whether the disclosed cause points to something systemic or a one-off is the open question.
