Atlas maintenance Notification should include description of maintenance
Whenever Atlas wants to do maintenance, it is sending email alert about the timing of maintenance. In addition to that we are requesting information about the nature of maintenance also like Mongo patching , BI connector upgrade or increasing no of connections etc. This will give us the information about the work and we can broadcast the same to our counterparts so that they can also use the product efficiently.
To be transparent with you, we built MongoDB Atlas so that you would not need to worry about lower-level implementation details like maintenance of instance replacements, operating system patches, and software patches.
We've also built many key capabilities into MongoDB and the drivers to ensure that maintenance represents as little a disruption as possible (ranging from auto-failover, to retryable reads and writes, to our Test Failover button for chaos testing).
If maintenance represents a problem for your applications, please open up a proactive support case so that our team can help get to the bottom of what's going on in your application code. We will continue to make investments to reduce the impact of maintenance over time and have introduced maintenance windows as a pressure valve for customers that want to control the timing of rolling maintenance.
