Planned Maintenance: Telehouse

Posted: Tuesday, April 1st, 2014 at 14:38 by Steve Lalonde

Wednesday 9th April 2014 00:00 – 04:00

During the above maintenance window we will be upgrading the software on telehouse-north.core.enta.net and telehouse-east3.core.enta.net, this will require the routers to be rebooted.

No customers are directly connected to these routers and traffic through the routers will be rerouted over alternate paths before the upgrade work begins.

Each router will be offline for approximately 30 mins.

Planned Maintenance: Installation of new core routers.

0:01 – 06:00 Friday 4th October 2013

During the above window we will be installing additional core routers in both Telehouse East and Telehouse North

The new routers will be connected to the existing routers and several core links will be moved to the new routers. Where a core link is being moved traffic will be switched to alternate paths before the link is moved.

No customer circuits will be moved during this work and no downtime is expected.

Emergency maintenance: telehouse-north.core.enta.net

6th October 2010 04:00 – 04:30

During the maintenance window above, the telehouse-north.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.

Note: this router is also known as telehouse-north0.core.enta.net

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.

Planned Maintenance: Telehouse North

Friday 22nd Jan 2010, 00:01hrs – 06:00hrs

During the maintenance window above, old fiber blade will be replaced as well as the IOS on the router will be upgraded to resolve some configuration issues. This software upgrade will require a reboot of the router which should take less than 30 minutes to complete, during which all directly connected customers will be out of service. Any traffic that would normally be routed through this equipment will route via alternate paths.

Outage: London to Manchester

Posted: Thursday, December 17th, 2009 at 10:41 by Phil Davies

The  link between London and Manchester is currently down. A fault has been raised with our provider and updates will be made as and well they are available.

Traffic usually on this route is using an alternative path, there may be a small increase in latency due to the change in routing.

  1. Steve Lalonde says:

    Service was restored at 05:15, engineers closed the fault at 07:30
