Node4 have experienced instabilities within the core network affecting servicing including MPLS and internet transit. Engineers are currently investigating.

Update 22/08/16 19:19 – Engineers have identified the root cause.  A software failure/crash on a core router (core dump). No changes where being made to the router at the time. This will be escalated to vendor TAC for further investigation. This router has been in operation without issue for several months, therefore we expect this to be a single occurrence however we will take advise from TAC on the next course of action.

 

 

 

Node4 customers may have experienced some disruption to transit services this evening. This was caused by a large scale DDOS. Engineers identified and then black holed the targeted IP range which resolved the issue. Engineers are currently working with the affected customer.

 

### Emergency Maintenance – VCD.n4cloud.co.uk – 19/09/16 22:00 – 00:00 ###

On 19th September 2016 between 22:00 and 00:00 Node4 engineers will be performing some emergency maintenance on the vCD.n4cloud.co.uk platform to patch the Cells following a support call with VMware. There will be some disruption to the vCD.n4cloud.co.uk page during this time however there will be no interruption in service to any virtual machine. If you need access to a virtual machine during this period please contact the Service Desk (support@node4.co.uk)

Telehouse have informed us that they will be performing emergency power maintenance within Telehouse North, which is a Node4 POP. The maintenance will require one of the two power feeds to our rack to be dropped for up 3 hours commencing 21:00.

The majority of equipment within our rack is dual powered however there are some devices, such as NTE and fibre/copper converters, which are not therefore some services may be affected. We will have an engineer on site during the maintenance window to monitor and make any necessary changes.

Update 21:30 – As result of losing the B feed some services have been interrupted however these were quickly restored.  At risk notification is still in place until secondary power feed is restored.

Update 22:05 – All clear has now been issued. Both power feeds have been restored. During the restoration one device needed to be rebooted. This caused a brief loss of connectivity (21:58-22:03) for a limited number of customers with services terminating in Telehouse North.

 

 

On 21st September 2016 between 21:00 and 23:00 GMT Node4 Engineers will be performing scheduled maintenance on the login page for https://vcd.n4cloud.co.uk. This work will not cause any service disruption to hosted machines however there will be a period when the login page for the site is unavailable.
As part of this work the ability to login to https://vcd.n4cloud.co.uk will be removed and customers using this platform will need to navigate to https://portal.n4cloud.co.uk where they will be able to login using existing credentials. This information will be communicated on the old web page. If you require access to a VM during this period please contact the Service Desk (support@node4.co.uk) and an engineer will be able to assist.

Note: this work is not related in any way to https://vportal.n4cloud.co.uk
