Background

On Friday 26th May, engineers will be upgrading software on N4Protect firewall hardware at both our Wakefield and Northampton datacentres. This is required to resolve a number of known issues, enabling N4Protect to continue providing a dependable security service to our customers.

N4Protect is deployed in a highly available cluster and firewalls will be upgraded linearly, as a result services are expected to failover while each firewall is upgraded.  However, we are issuing this notification in case of any unexpected impact from this planned maintenance.

Impact

At Risk – Friday 26th May 22:00 – 02:00 GMT
No downtime is expected, however services will be considered “At Risk” for the duration of the window.
Updates will be posted to N4Status during this planned maintenance.

If you have any problems with your connection after this time, or if you have any questions regarding the maintenance at any point, please call Technical Support at 0845 123 2229 or visit www.node4.co.uk/support.
