Christmas moratorium 2017-2018
Posted by David Croft on 13 November 2017 06:36 PM
Please be advised of the following Christmas moratorium scheduled on
our network.

Start date: Tuesday, 12th December 2017
End date: Friday, 5th January 2018

Purpose:

In line with industry best practice, we and our suppliers will be
instituting our annual change freeze between these dates in order to
protect customer services.

Services affected:

All.

Impact:

There will be an moratorium on changes across our network during this
period. Provision activities may be delayed and lead times will be
impacted if they fall within or after this window. Repair activities
will not be affected.

If we carry out any maintenance activity during this window, it will
be for emergency reasons and will be carried out to protect customer
service and the network from an uncontrolled loss of service.

Please ensure any new orders are submitted in good time to avoid being
affected by this window.

Please note that a few of our suppliers have extended moratoriums
greater than the above time period and our ability to deliver certain
orders may be impacted by this. Customers will be advised at the point
of order if this affects them.

Regards,

David Croft

[Core Network] Maintenance window 17th November 2017
Posted by David Croft on 25 October 2017 03:49 PM
Please be advised of the following maintenance window scheduled at our
Telehouse East (LNPOP01) site:

Start date: Friday, 17th November 2017
Start time: 19:00 GMT (UTC+0000)
End time: 23:59 GMT (UTC+0000)

Purpose:

We will be performing router upgrades and applying security updates.

Services affected:

None directly.

Impact:

LOW.

This site is a network PoP and does not directly serve customers. The
site will be taken out of service prior to work commencing and the
network will operate with reduced resiliency. We are therefore
expecting no operational impact from this work.
