MDPI Services Restored Following 18 September Outage

On Friday, 18 September 2026, MDPI experienced a service disruption that temporarily affected access to MDPI.com and several related platforms, including our submission system.

Following a failure within our infrastructure service provider's facilities, our technical teams worked continuously with the provider to safely restore the affected services. MDPI.com was brought back online first, followed by our submission platform and other affected systems. All services have since been restored and are operating normally, and our teams continue to monitor our systems closely.

No user data was lost or compromised as a result of the incident.

We recognize that access to our website and submission platform is important to authors, reviewers, editors, readers, and other members of our community, and we apologize for the disruption and inconvenience caused.

We are working with our infrastructure provider to complete a full review of the incident and its root cause. In parallel, we are reviewing our infrastructure and resilience measures to identify additional steps that can reduce the risk and impact of similar disruptions in the future.

We appreciate the patience and understanding of our community while our teams worked to restore services.
