From Bitfinex
"Dear Bitfinex user,
We are rapidly approaching the last phase of our data migration to dedicated bare-metal servers, with scheduled downtime commencing on Monday 7th January at 10:00AM UTC.
This means that tomorrow for a period of up to seven hours Bitfinex account holders will be unable to trade or access their wallets.
There are no actions you need to take in advance of the data migration tomorrow, but please do pay particular attention to the following information:
All funds will remain safe and unaffected throughout the entirety of the migration and will not be at risk at any point throughout the update. No orders will be executed during downtime. All open orders will be kept (regardless of price movements) and resume once the platform is back online.
Users will not be liquidated during downtime. However, traders should be aware that if the price moves significantly during this time, they are at risk of liquidation as soon as the platform is reopened and should therefore take necessary precautions. We kindly ask all traders to review their margin requirements and assess the risk of market movement on their open margin positions before entering the maintenance window.
Whilst the migration is due to take place tomorrow at 10:00 AM UTC, we will continue to monitor the market and if deemed too volatile, will reschedule to more typical conditions. You will be the first to hear of any changes.
Tomorrow we will be in close communication to ensure you are fully up to speed. We will alert you 1 hour before the migration commences, and our status page will be regularly updated with our progress. We will send another email 5 minutes before the platform re-opens and trading will start 5 minutes after the platform is accessible again.
We have created a specific FAQ here, but if you have any outstanding queries, please do not hesitate to get in touch with our support team here.
We appreciate that up to seven hours is a significant length of time in digital asset trading, and we thank you for your understanding and patience whilst we take these necessary measures to make our platform even greater (please see our announcement for further details).
Rest assured we are working quickly to make this transition as smooth as possible without compromising on safety or quality.
The Bitfinex Team"
