[Investigating] As of 09am 15th August 2018, Node4 have been aware of the discovery of a new “speculative execution side-channel" type vulnerabilities within Intel processors. Called L1 Terminal Fault (L1TF) or "Foreshadow", this vulnerability concerns processors with SMT technology which could allow malicious code running on one thread to access data from the other thread's L1 cache within a single core. Of the 3 discovered variants only L1FT VVM could affect Node4 Cloud services. L1FT / Foreshadow vulnerability is extremely complex to implement and only a proof of concept , developed in the laboratory, validated its existence. While there is currently no single fix for the vulnerabilities, a number of vendors have released suggested mitigations and remediation(s). As these are released, we’ll assess, test, coordinate and deploy accordingly across our environment. We will communicate to affected customers if actions that would impact their environments are required. Node4 takes security of its clients and its own infrastructure extremely seriously and work closely with our partners, manufacturers and publishers, to improve the security of our infrastructure every day. This complex and evolving situation will be monitored by Node4 Security Operations Centre to ensure our customers’ environments are protected, and we’ll do that in the least impactful manner possible.

Description

We are performing some upgrade works on our Uninterruptible Power Supply (UPS) system in DC3 Leeds over the next couple of months We do not expect any service interruption during these works, but there will be periods when we are commissioning new equipment that will be classed as "elevated risk" with short periods of maintenance bypass and running on generators. All these works are restricted to either the A or B feed at any one time. The alternate feed will always be available and UPS backed during any works. We will publish separate notifications for each period of work, but the current program has commissioning dates as follows 20th May: Add 4th UPS to B Feed (purple) 28th May: Reconfigure A feed to prep for expansion (orange) 10th June: Add 4th UPS to A feed (orange) 24th June: Final reconfiguration of A feed and sync panel There will be additional works (phase 2) after this in July.

Description

Core Network Planned Network Maintenance - CHG0034636– reduced resiliency 23-05-2019 00:01:00 – 02:00:00 BST At part of ongoing network upgrades to increase network capacity engineers will be adding an additional 10GE link on the MPLS network between London and Northampton (DC-4) Data Centres. In order to minimise risk during this change MPLS and Internet traffic will be re-routed away from the current inter-DC links. The new circuit will be added and validated follow which traffic will then be re-routed back over the link. We do not expect any noticeable impact on customer services during this change however as we will be operating at reduced resiliency during the re-routing. 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. Support & Feedback Our network operations engineers will closely monitor the work and will do everything possible to minimise any inconvenience to you. If you have any problems with your platform 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 node4.co.uk/support. While it is important for Node4 to perform maintenance such as this to ensure the quality of our network, we do everything possible to minimise any inconvenience to our customers.

Description

On Tuesday 21st May 2019, NODE4 Engineers will be carrying out work to upgrade to NODE4’s vCenter in Northampton and Wakefield. This upgrade is to allow the Cloud Infrastructure team to progress the NODE4 Cloud Infrastructure upgrade roadmap. Change Window - Tuesday 21st May 21:00 – Wednesday 22nd May 03:00 During the change window, customers may experience disruption to vCloud Portal (portal.n4cloud.co.uk) access as well as limited functionality. Updates will be posted to N4Status during this planned maintenance.

Description

Core Network Planned Network Maintenance – reduced resiliency 06-06-2019 00:01:00 – 02:00:00 BST As part of ongoing network upgrades to increase network capacity, engineers will be removing one of the core network routers that doesn't have the required scalability from the active core path. This work is being carried out at our Manchester Equinix point of presence. In order to minimise risk during this change MPLS and Internet traffic will be re-routed away from the current inter-DC links. We will then remove the router from the active core paths, before moving traffic back to the new topology. 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. Support & Feedback Our network operations engineers will closely monitor the work and will do everything possible to minimise any inconvenience to you.
