Outage on 2nd october

Published: 03/10/2019

At 15:15 BST on Wednesday 2nd October our monitoring system alerted us of a network outage that affected most of our services.
We had Openreach onsite at the time installing more fibre connections for redundancy to our datacentre when there was an outage. At first we thought this was related however we narrowed the issue down to SSE network to network interface with Virgin media of which we use for our fibre to datacentre connections and contacted them to report this.
They confirmed they had an issue with a cross-connection within a London datacentre and raised a support issue under their SLA. They resolved the issue at 17:30 however we still had some services down. This was down to our network system in our datacentre requiring a reboot to restart again. All services were resolved at 18:15.
We are addressing these issues and working on building a high availability network in our new datacentre and we can assure you we will carry on with the outstanding service we are known for. Openreach are currently installing new systems and fibre cables for higher availability. This work is due to be completed by the 13th of October. We have reviewed and made changes to our uplinks, network routes and SLAs since the last outage in August.
In the meantime, if you still have any concerns and would like to arrange a meeting or to visit our new datacentre please get in touch with us.
