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

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

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.

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.
