Following on from recent network incidents it has become necessary to schedule a series of emergency maintenance windows at the above time in order to undertake IOS upgrades to the routers specified below. Each update will require a reboot of the device and hence anyone directly connected will experience a brief outage. It is anticipated that each such outage will last approximately 15 minutes.

Please also be aware that the network will suffer short periods of instability during the entire window due to routing protocol re-convergence.

The following routers will be affected on the following days.

Emergency maintenance: telecity-hex.core.enta.net

Posted: Friday, October 1st, 2010 at 12:17 by Steve Lalonde

7th October 2010 01:00 – 01:30

During the maintenance window above, the telecity-hex.core.enta.net router will be rebooted for a software upgrade to resolve some configuration issues. This should take less than 30 minutes to complete, during which time all directly connected customers without backup services will be off line.

This work has been scheduled to coincide with existing planned engineering work to reduce the impact on our customers.

  1. Steve Lalonde says:

    Due to issues with last nights emergency maintenance work we have postponed this work. It will be rescheduled for a later date.

Planned Maintenance: DSL core network

Posted: Saturday, July 17th, 2010 at 12:58 by Steve Lalonde

Wednesday 11th August 2010, 00:01hrs – 06:00hrs and
Thursday 12th August 2010, 00:01hrs – 06:00hrs

During the maintenance window above, We will be performing essential maintenance on our DSL network involving software upgrades and changes to the links between the DSL core sites at Interxion and Telehouse adding additional capacity and increasing resilience.

There will be several short (up to approx 15 minutes) outages during this work while routers are rebooted and DWDM equipment is added to the fibre paths between the sites.

We apologise for any inconvenience this may cause.

  1. Steve Lalonde says:

    We have finished the planned work for tonight, all systems are working normally.

    If your service is not working please contact support via the usual channels.

Outage: Telehouse-north0.core

Posted: Friday, January 22nd, 2010 at 13:08 by Martyn Haynes

We are seeing issues accross the network that inital investigation shows could be related to a possible fault in Telehouse-north0.core. Our engineers are investigating these issues as a matter of urgency. Further information will be provided when available.

  1. Martyn Haynes says:

    We have stabilised the issue however it is not resolved. An Engineer is tasked to site to investigate further. Further updates will be posted when available.

  2. Steve Lalonde says:

    We need to reload the router to eliminate the IOS version as the cause. the reload will be at 15:55

    All traffic that flows via the router has been rerouted over alternative paths where possible, all directly connected customers will experience an outage of approx 10 minutes.

  3. Steve Lalonde says:

    The router is now operational again we will keep the traffic routed over alternative paths while we monitor the system.

  4. Steve Lalonde says:

    We are now routing approximately 1/3 of the normal traffic back through the router, the current priority is to get all the resiliency that relies on this hardware operating as normal. This should be achieved in the next 30 minutes.

    We will continue to monitor the situation and update.

  5. Steve Lalonde says:

    All resilient links are now operational, we are continuing to route traffic over alternate paths.

  6. Steve Lalonde says:

    After monitoring for more than 24 hours, the router is stable and functioning normally, We have now routed traffic back on to the optimal paths.

  7. Richard Partridge says:

    There is now an outage report available for this issue. It can be found here.
