[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.

N4Cloud Derby

Description

A bug has been detected in a cluster switch on the Derby shared storage platform. To address this issue we will be removing the cluster switches from the platform as they are not necessary in our DBY shared storage platform. During the process backend storage cluster traffic will be re-routed while the network switches are removed. During the failover of the storage cluster traffic there may be a slight increase in latency experienced on the platform, although there should be no loss of service. We would advise that customers with latency sensitive applications check services after the removal.

Description

New storage nodes will be added to our Wakefield shared storage platform. This process should not cause any loss of service, however during the process latency may be slightly higher than normal. We would advise customers with latency sensitive applications to check services prior to the work being carried out.

Description

On Thursday 25th April 22:00. After a number of issues with the ACI Generation One Leaf nodes, Node4 are making a large investment into the technology area to replace the problematic hardware. Therefore engineers will be adding additional new generation leaf nodes to the platform in preparation of service migration away from problematic Generation one hardware. Please note the maintenance window will ONLY include the addition of nodes into the platform and NO services will be migrated until further notice. Impact At Risk - 25/04/2019 22:00 - 25/04/2019 23:59 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. Whilst it is important for Node4 to preform maintenance such as this to ensure the quality of our network, we do everything possible to minimise any inconvenience to our customers. We appreciate your patience and welcome feedback. Regards Node4 Technical Support.

SIPLink Derby

Description

On Monday 29th April, Node4 engineers will be performing a minor software version upgrade on our Derby SIPLink v2 platform. This upgrade is recommended by the vendor and contains a number of bug fixes relevant to the Node4 SIPLink platform. Upgrades of this type are expected to be seamless with no downtime. During the maintenance window the individual servers in the cluster will be rebooted therefore the platform will be operating with reduced redundancy. As such the platform should be considered At Risk for the duration of the maintenance 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.

MPLS Services

Description

Core Network Planned Network Maintenance – reduced resiliency 02-05-2019 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 the Wakefield (DC-3) 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.
