N4Portal issue with Chrome Browser
Posted by on 17 October 2017 09:08 PM
October 17, 2017 9:08PM BST
Identified - As part of a chrome update this weekend people may be experiencing issues with the portal when using a chrome browser. This is down to an update released for Chrome at the weekend that upgraded the embedded version of flash that is no longer compatible. There is currently no fix for this though there are workarounds published involving modifying the version of flash used. Our recommendation is to use a different supported browser, or if accessible to your environment the N4Cloud Portal which is not affected by this issue

October 17, 2017 9:44PM BST
Identified - As there is a workaround in place by not using Chrome the status is being changed to Operational but the incident will remain open for further updates

Scheduled - Background

On Sunday 15th October, engineers will be performing maintenance on N4Protect firewall hardware at both our Wakefield and Northampton datacentres. This is required as part of investigations in to a suspected issue, as directed by vendor technical assistance.

N4Protect is deployed in a highly available cluster and firewall maintenance will be completed one at a time, as a result services are expected to failover. However, we are issuing this notification in case of any unexpected impact from this emergency maintenance.


Impact

At Risk – Sunday 15th October 22:00 – 02:00 BST

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 connection 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 www.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. We appreciate your patience and welcome any feedback.

Scheduled - Following an incident with a core router at the Wakefield Data Centre this morning (12/10/17 06:53-07:05 BST) it is necessary for Node4 engineers to perform emergency maintenance on the device. The router is currently operating without hardware resiliency and therefore we intend to carry out maintenance to restore this resiliency. We are currently waiting on advice from TAC on how best to proceed with this process. It is likely we will need to replace the primary routing engine module and then failover from backup to primary to test resiliency. This work has a high potential to cause a service outage (if the failover process does work correctly and occurs non-gracefully). Should this occur we expect MPLS, Internet Transit and Cloud services in the Wakefield DC to see some service disruption for up to 15 minutes. Services traversing the Wakefield DC may also experience some disruption while routing convergence takes place.

Further updates will be provided during the maintenance window.

October 13, 2017 12:01AM BST
Active - Maintenance about to commence - further updates to follow

October 13, 2017 12:37AM BST
Active - Work has now been completed. Full resiliency has been restored. There was no service impact as a result of this work. We will continue to continuing to monitor until 01:00 and then close maintenance window.

Completed - Maintenance window now closed.

Emergency Maintenance Firmware Upgrade Core Switch - NHT
Posted by on 12 October 2017 06:59 PM
September 26, 2017 9:54AM BST
Scheduled - On Thursday 12th October 2017 @ 19:00 Node4 Engineers will be carrying out work to upgrade the firmware on one of 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.

We therefore deem this window AT RISK until 12th October 2017 @ 23:30.
