IDENTIFIED about 1 month ago - at 10/31/2025 03:02PM

We’ve identified the root cause of this issue and are actively working to implement a fix.

Whilst the KYT UI is still down, some services have returned to normal (alerts APIs), and it appears that transfer APIs were unaffected by this incident.

Other services are actively coming back online, and we expect all APIs to be back up and running momentarily.

We will continue to monitor this and work to ensure services are restored to a healthy state.
