You have recently launched an E-commerce application. During the festive time, many customers called and reported application unavailability. Before the festive reason, with lesser load, the application was working without any issue. What should you do?
1) Investigate and identify the cause of the application unavailability
2) Increase the server capacity to handle higher load
3) Apologize to the customers and offer compensation
4) Ignore the issue as it was only during the festive time
