Description

<b>Subject: </b>Planned Maintenance Notification - CRQ000001306995 <b>Change ID: </b>CRQ000001306995 <b>Description: </b> Our MNO partner will be performing planned maintenance to update their route advertisements. This is part of ongoing work to improve network security. <b>Expected Impact: </b> We do not expect any service disruption because traffic will use our redundant MNO links. However, there might be a small chance of a brief interruption of up to one minute if any unforeseen issues occur. <b>Reason for Change: </b> To support continuous improvement, we have asked our MNO partner to update their filtering policies. This will enhance security and help improve network performance, scalability, and service capabilities.
