Please be advised that we are aware of a brief outage on the IP Voice service at around 11:15am.

It would appear that services have now returned to normal, however we have raised this with BT and are working with them for confirmation.

We will release an update as and when we know more.

Regards,

Michael

Please be advised of the following emergency engineering works on the IP Voice Services platform:

Date: Tuesday 06/11/2012 from 22:00 to 23:00

Purpose

The Engineering Team will be carrying out emergency works to change the media SFP modules in one of the SBC's making up part of a carrier side SBC cluster on 06 /11/2012 between 22:00 and 23:00.

This is being done as a precautionary measure based on analysis of recent logging that has highlighted a possible hardware failure in relation to these modules.

Impact

There is no expected effect on service as a result of these works as the affected SBC will be removed from service without any effect on service and reinstated once work is completed.

Our sincere apologies for the short notice of these works.

Please be advised of the following maintenance window scheduled on our network:

Date: Sunday, 11th November 2012

Start time: 15:00 UTC

End time: 19:00 UTC

Purpose

Firewall and IDS maintenance at our Comtec House (LSREI01) data centre.

Impact

The project plan for this work calls for no customer-visible outage due to the redundant nature of these devices. However we are also aware of a defect in the current software version that means there is a likelihood of a few minutes loss of service during this window for hosted customers at Comtec House.

Comtec NOC is tracking this issue under ticket [#NGP-595-16849].

Regards,

David Croft

Please be advised of the following planned engineering works on the IP Voice Services platform:

Date: 21:00 to 21:30 on Saturday, 10/11/2012

Purpose

The Engineering Team will be changing the DNS resolved IP Addresses for linksys.yourservices.co.uk and soundpoint.yourservices.co.uk on 10/11/2012 between 21:00 and 21:30. These will be changing to:

soundpoint.yourservices.co.uk - 85.119.59.22

linksys.yourservices.co.uk - 85.119.62.8

Impact

Expected impact is LOW.

Please ensure any restrictions you have in place relating to these URL's are updated to reflect the above. These are the URL's used by Linksys and Soundpoint IP phones for the automatic provisioning process so failure to enable access to these will prevent phones from functioning correctly.

Please be advised of the following planned engineering works on the IP Voice Services platform:

Date: 22:00 to 23:00 on Sunday, 01/07/2012

Purpose

The IPVS Engineering Team will be adding additional paths between internal switches to improve bandwidth and resilience. Internal traffic flows will be moved to this new path.

Impact

Whilst we expect no service disruption as a result of this work, due to their nature there is a very low risk that some customers may experience a brief interruption of between 0-30 seconds as the services automatically re-route to the new connections.

We will be continually monitoring Voice and Network services throughout the period of works to ensure that no unforeseen issues are experienced.
