Posted by on 06 July 2018 04:44 PM
July 6, 2018 4:44PM BST
Investigating - Our monitoring has alerted us to a 10Gbps circuit dropping between Derby and Global Switch. This has flapped as such we have costed this circuit out so traffic re-routes. We have raised this with our supplier whom are currently investigating this.

We will provide updates as we receive them.




July 7, 2018 12:19PM BST
Monitoring - Updates from provider they have investigated the circuit and the flapping that was occurring, they have given an all clear.

We are going to monitor the circuit for a number of hours before routing traffic over this and bringing it back into full operation.

July 7, 2018 10:36PM BST
Resolved - The circuit has remained stable throughout the day, so we have removed previously applied costings to allow traffic to traverse the network as normal.

Scheduled - Background
On Monday 2nd a Cisco Nexus switch within the Northampton/DC-4 Cloud Environment failed with a hardware fault.
Engineers attempted to replace the switch during an emergency maintenance window on Tuesday morning however the replacement switch failed to join the fabric correctly and platform instabilities occurred. The switch was therefore disconnected.

Cisco TAC have been unable to determine root cause at this time and are unable to confirm a timeframe for this. We do however need to take steps to restore full resiliency.

Engineers have continued to work on the Northampton environment. They have performed a number of key changes in order to reduce the impact and risks associated with the installation of the replacement switch. At 01:00 BST on Thursday morning engineers - with remote support from Cisco TAC - will bring the replacement switch in to service again. Any potential impact will be reduced through the changes we have made although all services will be “at risk”.

Maintenance Window
05/07/18 00:00 – 01:00 (BST) Preparation
05/07/18 01:00 – 05:00 (BST) Replacement switch brought in to service, testing and regression window

Engineers will bring replacement LEAF switch back in to the fabric
Testing will commence to validate this is successful
Services will be re-enabled on the switch in a phased manor with continual monitoring and testing
Should issues occur we will take advise from Cisco TAC

Impact
The platform and all associated services will be at risk during this process.

Please raise a support ticket or contact you customer services representative if you require further information.

Support & Feedback
Our network operations engineers will closely monitor the work and will do everything possible to minimise any inconvenience to you.

Removal of Node4 STUN Service
Posted by on 03 July 2018 01:18 PM
April 16, 2018 8:42AM BST
Scheduled - This notice is intended for Node4 SIPLink customers who use Node4's STUN service

* What is STUN?
STUN ("Simple Traversal of UDP over NAT") is a protocol that aims to resolve the issues that some Customers experience when using Network Address Translation (NAT) with their SIP endpoints. This is defined by the IETF in RFC3489 and RFC5389.

* What service does Node4 Supply?
Node4 host several STUN servers. These are public facing servers and can effectively be used by anyone - not just Node4 customers. They do not have any connections to the Node4 SIPLink platform or any other back-end systems.

Current servers include:
stun.node4.co.uk
stun1.node4.co.uk
stun2.node4.co.uk

STUN does not form part of the SIPLink Service Schedule or contract and has been provided as a free of charge add on service. It does not carry any service guarantee or SLA.

* Why are Node4 retiring this service?
Usage of STUN by Node4 SIPLink customers is limited and is continually decreasing. This is mainly due to improvements in ALGs and the fact that most PBXs are now able to handle NAT in a more sophisticated manner.

In addition, STUN is not provider dependent which means that customers do not need to use a Node4-provided service. There are many publicly available services that can be used instead, should customers still require access to STUN.

In most case, where a PBX Vendor requires STUN, they will offer their own publicly-accessible solution.

* When will this happen?
All STUN servers will be disconnected 1st July 2018

* What if I depend on STUN?
We would recommend discussing with your PBX vendor as they may have an alternative solution for NAT traversal, or may have their own STUN server available.

If you have any concerns or questions relating to this, please log a support ticket via the Node4 Service Desk and we will endeavor to assist you in finding a solution.
