Scheduled - Background

Following the investigation into an issue, we are seeing with calls following through our network. We require an emergency maintenance window on Debry SIP Link Platform.

This will be to conduct configuration changes on a set of switches connected to the platform.


The impact of this work should be minimal these are resilient links and we will conduct each change individually. All efforts will be made to keep downtime to a minimum.

All links are redundant and will be changed one at a time. As such we do not anticipate disruption however SIPLink should be considered "At Risk" during this time.

If you have any questions please contact the Node4 Service Desk at 0845 123 2229 or raise a ticket via the support site

Updates will be posted to N4Status during this planned maintenance.
