## RCA **What happened?** After automatic Azure update by Microsoft, few dependencies begin to show resource problems on high load, eventually degraded performance and cause some clients not see their signature in outlook. **How did we respond?** We applied several changes to the codebase and upgraded dependencies to the latest and stable version of .NET6. We implemented multiple instances to handle high loads and optimize performance. **How do we improve and prevent this in the future?** We added additional test frameworks and more emphasis on QA.
