I would like to address the unscheduled restart that occurred yesterday. In the morning, we were upgrading the backup system and an error in the updated code caused a shutdown on the live server rather than the backup server. This issue has now been corrected.
Over the past two days we carried out extended morning maintenance, which required multiple reboots. That work is now complete, and we are moving forward with a fixed restart time of 7:00 AM VZT each morning. Please note that the daily scheduled maintenance window will remain open until 10:00 AM to provide flexibility in case additional time is required.
We have also updated the backup schedule. Backups will now run at 1:55 AM, 3:55 AM, 6:55 AM, 6:55 PM, and 11:55 PM. During these times you may notice a brief period of lag. These times were chosen carefully to coincide with the lowest usage levels on the servers. Our system automatically copies and restores everything to a backup server located in a second site. This ensures that in the event of a serious outage that cannot be resolved quickly, we can restore services with minimal disruption.
Looking ahead, we will be conducting simulated tests on additional backup servers in the coming months. These tests will cover secondary, tertiary, and quaternary backup servers, and they will not cause any downtime or data loss.
