Feb 16, 02:00:48 GMT+0 - Postmortem - On February 15th, our primary hosting facility experienced an infrastructure-level power failure that impacted several nodes, including systems supporting our primary data site. As a result, the primary data site was temporarily unavailable. We initiated full infrastructure rebuild procedures and performed comprehensive data integrity validation before restoring and republishing Benchmark and Crypto feeds. Full restoration was completed in approximately 2.5 hours, followed by a controlled and gradual reactivation of dependent services. Our secondary site remained fully operational throughout the event and was designed to support this exact scenario. Enterprise and Institutional clients ingesting crypto feeds via the secondary endpoint should have experienced minimal or no disruption, assuming standard integration configuration. We are continuing to review the event in coordination with our infrastructure provider.
