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.


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.
