Beginning overnight, our authentication systems experienced intermittent failures, causing some users to be unable to log in or authenticate to services. At 08:00 the incident escalated significantly when the primary node in our authentication cluster failed, removing the redundancy that had been masking the intermittent faults and resulting in a broader loss of authentication availability.
During the affected period, users may have experienced failed or delayed logins, session authentication errors, and intermittent access issues across dependent services. The impact was intermittent in the earlier phase and became more pronounced following the primary node failure at 08:00.
Our engineering team responded to recover the authentication cluster and restore normal operation. Services began to return from 09:15, and authentication availability was progressively restored as the cluster stabilised. The cluster has since remained stable with no recurrence of the fault.
Our engineers are now conducting a full root cause investigation to determine the underlying trigger of both the intermittent failures and the primary node assertion. Once identified, we will implement corrective and preventative measures to improve the resilience of the authentication stack and reduce the likelihood of a similar incident in future.
We apologise for any disruption this may have caused and thank you for your patience.
If your services have not been restored, we would kindly request that you restart your router. If this does not restore your service, please contact our customer care team. https://www.internetty.uk/contact-us
