How does Mimecast ensure minimal impact during server downtime?

Mimecast ensures minimal impact during server downtime primarily by rerouting email through their cloud infrastructure. This approach allows emails to be processed and stored in an alternate environment, ensuring that mail flow remains consistent even if there are issues with on-premises servers. The cloud infrastructure is designed to provide high availability and redundancy, which means that even if one server or service experiences downtime, the system can seamlessly redirect traffic to operational resources without users being significantly affected.

This strategy not only maintains business continuity but also minimizes delays in email delivery, ensuring that users can still send and receive emails during unexpected server outages. The seamless transition to the cloud infrastructure is a key benefit of Mimecast's architecture, delivering reliable email services regardless of local server performance.
