Scheduled - On Wednesday 13th June 2018, Node4 Engineers will be carrying out work to upgrade the firmware on one of the core switches upstream to the cloud platform at Northampton

We expect failover to be around 1-3 minutes or less while we re-route traffic around the core switch, you may experience slight degradation across MPLS and Internet transit paths while traffic is re-routed.


At Risk – Wednesday 13th June 00:00 – 04:30

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.
