Scheduled - Upgrade work to move to a different version of JUNOS software that is not affected by the bug.

We will gracefully move as much traffic as possible away from the device. There will be a few short spells of downtime for customers directly connected as we fail over the routing engines during the upgrade.

We do not expect the upgrades to take much longer than 20 minutes, however the device and services will be at risk for the full duration of the window.

Active - Engineers are currently on site work is now commencing more updates to follow.

July 30, 2017 2:59AM BST
Active - We have completed the upgrade of one of the routing engines.

This has been successful and we have now made this master for the MPLS PE device . Unfortunately due to delays outside of our control this has taken longer that we anticipated as such we need to extent the maintenance window to complete the backup routing engine upgrade.

We do no envisage any further outages following this.

More updates to follow.

July 30, 2017 3:28AM BST
Active - The second routing engine is upgraded and complete.

All services are showing normal operation.

We are completing final check before giving all clear.

July 30, 2017 3:37AM BST

Emergency maintenance on the Wakefield ACI Platform
Posted by on 28 July 2017 08:30 PM
July 28, 2017 11:14AM BST
Scheduled - On Friday 28th July @ 20:30 Node4 Engineers will be preforming Emergency maintenance on the Wakefield ACI Platform.

There is slight chance of impact due to a potential chassis reload, however the platform is highly resilient and we expect failover to be around 5 minutes or less while Layer 2 and Layer 3 protocols re-calculate. This will affect Internet connectivity and MPLS connectivity from the Wakefield cloud platform.

The platform will be deemed “At Risk” until Friday 28th July @ 23:30

Node4 has successfully completed the criteria required for HSCN compliance, including meeting rigorous third-party standards. We are one of the handful of organisations to achieve this standard and I am pleased that the public sector team can grow this market sector.”

“Now that Node4 is fully HSCN compliant, we are able to grow our presence in the health and care sector. We are able to provide our connectivity services and HCS collaboration platform to end users; and help the NHS and other organisations alike with security infrastructure challenges.
