During the above maintenance window, we will be updating our RADIUS servers to run a revised version of code. This code will fix an issue with new PPP sessions not being rate limited on connection whereby they have already exceeded there usage limit.

The RADIUS process on each server will be shutdown while the new code is applied and then re-started. This will be done 1 server at a time. Existing connections will remain online, however some accounting data maybe lost. New connections may be delayed in PPP while they are re-routed to an active RADIUS.

UPDATE01 – 22:45 This work started later than planned however is now complete. All RADIUS servers are running the updated code and have tested OK.

LON01 – 17/02/2016 – 23:00 till 03:00 – EasyXDSL – Maintenance *COMPLETE*

We have been advised by one of our interconnect providers that that they will be conducting a software upgrade on there core Junos router at Telehouse North between 23:00 and 03:00 on the 17/02/2016 from 23:00 – 03:00. This upgrade work will affect one of our fibre waves we use for DSL termination back in … Continue reading “LON01 – 17/02/2016 – 23:00 till 03:00 – EasyXDSL – Maintenance *COMPLETE*”

We have been advised by one of our interconnect providers that that they will be conducting a software upgrade on there core Junos router at Telehouse North between 23:00 and 03:00 on the 17/02/2016 from 23:00 – 03:00. This upgrade work will affect one of our fibre waves we use for DSL termination back in to our network at Goswell Road. DSL traffic traversing over this link will drop during the maintenance window, however should re-establish over an alternative link via Telehouse East which is unaffected.

The nature of these works include a reload of the Junos hardware at Telehouse North by our wave supplier and in theory should be the only disruption we see. Unfortunately sort disruptions like this will cause multiple DSL PPP session re-terminations as they flip back and forth between Telehouse North and Telehouse East as our network is designed to use the former where possible. Due this concern and avoiding any other unforeseen issues that will cause session drops during the maintenance windows, we will be manually shutting down the Telehouse North link at 22:00 on the night with the view of bringing it backup at 07:00 the following morning. This will limit the session drops to these times and provide a stable service throughout.

UPDATE01 – 17/02/2016 – 22:00
Traffic has been re-routed

UPDATE02 – 18/02/2016 – 09:05
Traffic has been re-routed

We are aware of an issue affecting inbound and outbound call routing on our network that started at 15:55 and are investigating as a matter of urgency. Initial diagnostics and reports show this to be an upstream carrier issue.

UPDATE01 – 16:10 Due to the nature of the outage, Automatic outbound re-routing to an alternative carrier has been intermittent as the carrier suffering the issue has been going on and offline. We have therefore manually re-routed outbound calls and can see them terminating OK. We are continuing to investigate.

UPDATE02 – 16:15 Further investigations are showing our BGP session to the affected upstream carrier as being intermittent. While reviewing the link we have received notice from 1 of our fibre providers that they have suffered a fibre issue in the Docklands area and this is causing there network to re-converge. Outbound calls continue to terminate correctly, however inbound calls via this upstream provider may be intermittent.

UPDATE03 – 16:45 We have seen the link stabilise and inbound calls from the carrier terminating OK. We are continuing to route outbound calls over alternative carriers as a precaution.

Unfortunately this device was not announced to our network by our supplier within our DSL BGP session, Therefore we where unable to route PPP responses back to this device. The device has been removed from our suppliers device pool and services are terminating back to us via known L2TP gateways. Service has now returned to normal. We apologize for any inconvenience caused.
