We are currently investigating an issue affecting Reactor graphs, which may prevent some graphs from loading correctly. KYT users may also experience delays in real-time monitoring for Plasma. Our team is actively investigating. We do not have a workaround to share at this time. We will provide further updates here as soon as more information becomes available.

We are continuing investigating an issue affecting Reactor graphs, which may prevent some graphs from loading correctly. We are also investigating degraded performance affecting certain Risk API services. Customers may experience errors when calling some risk-related endpoints, and KYT users may also notice delays in real-time monitoring for Plasma. Our team is actively investigating and working to narrow the scope of the impact. We do not have a workaround to share at this time. We will provide further updates here as soon as more information becomes available.

A fix has been put in place and we will continue to monitor the stability over the next 48 hours. Reactor graphs should now be loading normally, and the broader degraded performance affecting Risk API services has recovered. We are continuing to investigate a separate issue limited to Plasma-related requests. At this time, any remaining impact should be limited to Plasma-specific API requests and related real-time monitoring. If you continue to experience issues outside of Plasma, please contact [email protected]. Next scheduled update at 17:00 UTC Monday 22nd.
