[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. Thanks Node4 Technical Support

Description

Updated 28/05/2019 with new dates 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) - COMPLETE 12th June (new date): Reconfigure A feed to prep for expansion (orange) 8th July: Add 4th UPS to A feed (orange) 18th July: Add 2nd UPS to Hall 4 Orange Feed 22nd July: Add 2nd UPS to Hall 4 Purple Feed Rik

Impact At Risk – 18-08-2019 22:00 – 19-08-2019 00:00 No downtime is expected, however services will be considered “At Risk” for the duration of the window.
