We have experienced a failure of one of the UPS devices that protects telford-dc3.core. We will shortly be undertaking work to replace the failed unit and restore full power redundancy. Services connected to or through telford-dc3.core should be considered at risk until the work is completed.

Further updates will be provided within the hour.

Tuesday 14/12/2010 01:00 – 06:00

Due to recent outages caused by gs1.core.enta.net, we will be upgrading gs1.core.enta.net to a higher specification device.  This should take less than 2 hours to complete, during which time all directly connected customers without backup services will be off line, all other traffic that normally passes through this device has already been rerouted via alternative paths.

We apologise for any inconvenience that this may cause.

Note: this is reposted due to the notification not being sent to mailing list subscribers.

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.
