Please be advised of the following maintenance window scheduled on our network: Date: Sunday, 13th July 2014 Start time: 10:00 BST (UTC+0100) End time: 14:00 BST (UTC+0100) Purpose: We will be performing software upgrades on our distribution switches at Reigate. Services affected: All services hosted in Comtec House, Reigate (LSREI01). Impact: Low. The redundant pair of distribution switches will be upgraded one at a time. Customers who have connected to both distribution switches per our recommendations will observe no operational impact as they will fail over to the redundant switch while the other is being upgraded. Customers who are single-homed to our network will observe a period of downtime of 5-15 minutes during this window. In the event that roll-back is required, there will be a further interruption while the original software is restored. No outage is anticipated due to the resilient nature of our network and transport out of Reigate, however services are "at-risk" during this window. IP voice services will be unaffected. Comtec NOC is tracking this issue under ticket [#GZO-670-71256]. Regards, David Croft Read more » | |

This is an incident notification regarding ADSL/FTTC services. Date: Monday, 9th June 2014 Start time: 11:00 BST (UTC+0100) End time: 11:44 BST (Workaround applied) End time: 10 June 12:22 BST (Resilience restored) Services affected: ADSL/FTTC customers, excluding Cloud Ethernet FTTC. Report: We experienced an issued that caused all ADSL/FTTC customers to disconnect and be unable to reconnect. We determined that this issue was not caused by our network and escalated this matter with our supplier. At that time we put into place a workaround allowing customers to reconnect using a backup route. Our supplier has determined that the root cause was a bug in Brocade software causing an invalid configuration to be applied to a core network router. This issue was resolved in conjunction with Brocade TAC. The primary path has therefore been tested and put back into service. At this time, all services are operating normally with full resilience. This is the final update. Comtec NOC was tracking this issue under ticket [#ROI-515-53554]. Best regards, David Croft Read more » | |
