Today the Secure Nodes development and operations team is conducting a major system upgrade. The tracking and payments system will be in a scheduled unavailability period starting at approximately noon Eastern time today, and expected to last for 6 hours.

These upgrades address system scaling and security, and will improve downtime, failover, and timeout issues.

These types of issues were expected to manifest at larger node counts, and was one of the drivers to moving testing to mainnet. Because of the large number of testnet nodes, currently over 600, the developers and sysadminds were able to identify and make improvements to the code and configuration before moving to mainnet.

After this upgrade, we will operate for some days on testnet to verify stability. Moving to mainnet is still a priority, and we want to make sure the system can handle thousands of active nodes with a minimum of support issues.

Thanks to everyone for both your participation and patience in this process!
