We will temporarily halt trading in our Testnet environment tomorrow Thursday, 7 July at 01:00 UTC to facilitate a minor upgrade to our database. Next Thursday, 14 July at 01:00 UTC, we will temporarily halt trading in our production environment for the same upgrade. The system will continue in cancel-only mode from 01:00 UTC until 01:05 UTC in both cases before the upgrade takes place; during this time cancel order requests will be processed. From 01:05 UTC, any order actions will be rejected. Deposits made during the whole period will be queued for processing. In both instances, the system is expected to be online again in cancel-only mode from approximately 01:30 UTC. Continuous trading will recommence from approximately 01:35 UTC. From the halt of trading until continuous trading resumes, there will be no Mark Price updates and hence no liquidations. While this is a minor upgrade, the process may take longer depending on a number of factors. During the upgrade, relevant updates will be shared on our status page.
