<h2>Migration Information</h2>
<p>New Servers of Windows Server Update Service (WSUS) and Windows Activation Service (KMS) in Region eu-nl have been set up to support latest MS features and products e.g. Windows Server 2025. These servers have new IP addresses and will be activated by changing the DNS entries on February 3rd, 2025. </p>
