Secure Email Cloud Gateway - Data Center Migration London to Frankfurt

Introduction

This document describes the process and impact of Cisco decommissioning our London data center for our Cloud Email Security (CES) hosted devices. 

Description

Moving services from London to Frankfurt datacenters involves the seamless migration of critical infrastructure, applications, and data between two major European hubs. This process requires careful planning to ensure minimal disruption to business operations, optimized network performance, and compliance with data residency regulations. By relocating services to Frankfurt, organizations can leverage improved scalability, enhanced security measures, and access to central European customers. The migration also involves key considerations such as latency, bandwidth optimization, and potential impacts on service-level agreements (SLAs) to ensure continued efficiency and reliability during and after the transition.
