🚨 Scheduled Maintenance Operating Now Expected downtime: 15 - 30 minutes Client systems will not be able to communicate with Deribit during this time. HFT Update: Single-Node Restriction Re-enabled We are re-enabling the restriction limiting each subaccount to one HFT node at a time. If a subaccount logs into a new node, any existing sessions on the previous node will be automatically disconnected. AWS PrivateLink We have expanded our AWS PrivateLink support to include three distinct gateway groups of ports (802x, 2802x, and 3802x) to facilitate access to different HFT nodes. ⚠️ Action Required Node Configuration: Restrict each subaccount to a single HFT node to avoid intentional disconnects. AWS Settings: If using PrivateLink, update Route53 Private Hosted Zones to support SSL on ports 443, 2443, and 3443.
