There was an event reported by our DDOS mitigation provider. We are currently working with them to better understand the scope and impact.

We are seeing improvements in availability for our Pod 6 customers. We are continuing to monitor the situation and will update.
During this incident, all Zendesk products and services were unavailable for some customers on Pod 6. A DDoS attack at the one of our data centers was identified by our DDoS mitigation vendor, who implemented a mitigation strategy. This mitigation resulted in some legitimate traffic being dropped, leading to subsequent accessibility issues to certain geolocations on Pod 6, primarily in North America. Once our DDoS response vendor adjusted the mitigation security profile, access for affected customers returned to normal. Our Operations team is working with the vendor to avoid these types of issues in the future.
