ICTO attaches great importance to the email service availability. In 2016, service level of Staff Email achieved 99.9% availability.
Keeping high service availability rate involves email system, hardware and storage level redundancy management to provide uninterrupted high availability to users. To move forward with continuous service improvements, ICTO has successfully implemented 3-location-architecture solution in October 2016, i.e. setting up an additional monitoring point upon two existing groups of email servers in 3 different data centers and server rooms respectively.
This architecture helps in monitoring and responds to the data center level failure event automatically. In addition, we have optimized the system maintenance procedures. Steps taken to optimize the performance level and it allows us to perform most of the system maintenance tasks without service interruption.
