[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.

Scheduled Maintenance - Northampton Cloud Core Switch Planned Maintenance

Description

On Thursday 17th January 2019, 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. Impact At Risk – Thursday 17th January 2019 22:00 – 06:00 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

Node4 Collaboration engineers will be performing a minor version upgrade on our SIPLink v2 platform. This upgrade has been advised by vendor TAC as a resolution to a bug a small number of customers are experiencing. 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.
