We have recently experienced instability on our xDSL platforms that would have affected some of our retail services; this would have included our bonding/failover platform and some single line services.  Service has been restored to the platform and customer connections should start to log on.

If you are still experiencing problems please try rebooting your router first and then call our Support Team on 0845 868 7848 (option 2).

We are currently experiencing an outage that is affecting all C&W Leased Line customers.  This is being looked into as a priority by C&W engineers and we are expecting an update shortly

Our internal phone provider has suffered a failure due to the datacentre outage at Meridian Gate. This is affecting our inbound calls. We are expecting it to be restored shortly, in the meantime please email in.

We have noticed a number of DSL tails briefly have logged off the network and back on. The root cause of the issue has not been yet identified but we are looking into it and will update customers accordingly.

Due to a core network issue O2 are currently routing all our ADSL traffic away from Telehouse and instead via Telecity.

This would have triggered a drop in sessions at around 11am. All load is currently routing via Telecity and we are awaiting further information from them.

Update 20/04/11 – After investigation O2 have discovered a configuration issue on their device at Telehouse, which is preventing MAC learning beyond a certain threshold.

General growth of the customer base over recent months has caused our MAC tables to exceed this threshold and the disparity between MAC learning at Telecity and Telehouse is contributing to a broadcast storm whenever there is a VPLS topology change.

Once O2 have agreed configuration changes these will be deployed to remedy the situation. O2 are now in a network freeze period until after the bank holidays, so it is likely that the majority of traffic will remain routing via Telecity for the moment. However, we have sufficient capacity at Telecity to sustain the load in the meantime. We are expecting the fix to be deployed without disruption to service.
