Resolved after 5 hours 56 minutes, affecting UK Network (London, UK) and USA Network (Tampa, USA), on October 12, 2026.
The incident earlier this morning was traced to a DNSSEC key-signing change implemented by ICANN over the weekend. This affected DNS resolution on the SpamExperts nodes, resulting in timeouts and delays in email scanning and delivery, which ultimately led to server overload. The issue has now been fully resolved, and all services are operational and functioning normally. We apologize for the disruption and any inconvenience caused.

We’re aware that some customers have experienced delays sending and receiving email today. This was caused by a fault on part of our mail filtering platform, which affects shared and reseller hosting and customers using our spam filtering service. Our engineers have stabilised the platform and delayed mail is now being delivered. We’re continuing to monitor it closely and will update this page when we’re confident it is fully resolved. There’s no need to contact us about delayed email. We’re sorry for the disruption this has caused.
