[Core Network] Service Alert 22nd May 2018
Posted by David Croft on 22 May 2018 05:35 PM
This is an incident notification regarding an outage on our core network.

Date: Tuesday, 22nd May 2018
Start time: 14:46 BST
End time: 16:44 BST (Final clear)

Services affected:

Intermittent partial and total outage across our network

Report:

A failure of a network device in our core network led to a cascade of
additional failures across the network.

Controlled shutdowns of portions of our network were necessary to
bring it back to a stable state in order to fully restore service.

Both the failure and the controlled shutdowns caused packet loss and
temporary routing failures to services hosted on or delivered through
our network.

Our network is built with a high level of resilience, and we and our
vendor are investigating as a matter of urgency how this failure was
able to have such a wide-reaching impact and the steps we will need to
take to prevent it recurring.

[ADSL/FTTC] Service Alert 10th April 2018 - Update 3
Posted by David Croft on 25 April 2018 10:37 AM
This is an incident notification regarding ADSL/FTTC services.

Date: Tuesday, 10th April 2018
Start time: 11:00 BST
End time: 11:58 BST

Services affected:

ADSL/FTTC circuits provided by TTB (excluding BT and Cloud Ethernet FTTC).

Report:

An incident occurred on the TTB network that caused a large number of
ADSL/FTTC customers to disconnect and be mostly unable to reconnect.
This affected all customers across all ISPs using the TTB broadband
network.

TTB have informed us that the outage was due to a faulty card at
Telecity Manchester which caused a backplane failure. The faulty card
was replaced and traffic was re-established.

The carrier has postponed all planned internal network changes in
order to investigate why the card failed and how this was able to
cause such a widespread outage in order to prevent a reoccurrence.

This is the final update on this service alert.

Purpose:

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

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

If we carry out any maintenance activity during this window, it will
be for emergency reasons and will be carried out to protect customer

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.
