SEDNA incident
Mail Ingress & Egress Outage: Customers in our EU Cluster unable to Send and Receive Mail
Resolved after 7 minutes, affecting SEDNA - www.sednanetwork.com, on December 10, 2025.
Estimated impact window: 08:40–09:05 UTC During this time, mail could not be sent or received in our EU cluster. Service has since fully recovered, and the system is currently healthy. All incoming mail from the affected window has been successfully reprocessed and no messages were lost. Any outbound messages that could not be delivered would have generated an NDR; if you received one, please resend the message. We are investigating the root cause and will provide further updates. In the interim, if you notice any mail delivery failures or unexpected behaviour, please let us know.
