The causes of error 503
During the upgrade to Magento 2, the system generates the file maintenance.flag to show the system is in maintenance mode. This can be useful to hind any problems that happen during the installation or upgrade of your customers.
This file is automatically deleted after the whole process is finished. However, sometimes it may not be automatically removed, or the file may be generated again in the system. Hence, the existence of .maintenance.flag file in Magento 2 system will show error 503 - Service Temporarily Unavailable.
