Scheduled Network Maintenance – London Data Centres

By UK2 Service Heartbeat

10 Sep 2013 16:50 – Our goal is to provide our clients with a robust and fully redundant network enabling high availability and up time for the services we offer. To achieve that goal it is necessary to schedule a network maintenance window which will introduce latency and brief periods of interruption. Our efforts to make proactive and controlled changes will significantly reduce the risk of unplanned events.

Maintenance Details
Location: London, UK data centres
Primary Router Upgrade Start Date & Time (BST/GMT +1): Tuesday, 17 September, 2013 10:00 p.m.
Primary Router Upgrade End Date & Time (BST/GMT +1): Wednesday, 18 September, 2013 2:00 a.m.
Secondary Router Upgrade Start Date & Time (BST/GMT +1): Wednesday, 18 September, 2013 10:00 p.m.
Secondary Router Upgrade End Date & Time (BST/GMT +1): Thursday, 19 September, 2013 2:00 a.m.

Description of Work: Network engineers will upgrade firmware on the redundant transit and peering routers requiring a full reload of each router. Because of the redundant design of the network, doing so will not interrupt the data forwarding for IP services located in the London data centres. During each router reload there may be brief periods of latency and packet loss as routes reconverge with IP transit and peering providers. Network engineers will closely monitor the work and will do everything possible to minimize interruptions.

Services Affected: All Internet facing services in all of the London data centre locations
Impact: Brief periods of interruption and latency during each router reload

Best regards,

Network Operations

Update: 18/09 11:10 – Primary Router Upgrade successfully completed, Secondary Router Upgrade to go ahead at 22:00 today.
