Our internal monitoring notified us immediately to the increased error rate and we began investigating.
It appears that the internal OpenAI key we use by default for chatbots that have not added their own key was deleted from our OpenAI account. We have verified account security and that this deletion was inadvertent.
After reissuing a new key and deploying all services should be back online. We apologize that this affected our customers, and will further restrict production key delete capabilities to make sure this won't happen again.
