Work is continuing to restore the affected service.
We have sent our Engineers to the data centre in Halifax to replace some affected hardware. Following supplier maintenance work last night, there appears to have been an unusually high level of optical light on the fibre, which has resulted in damage to the SFPs at both ends. They have now been replaced, and we are starting to see affected services come back online.
We will continue to monitor and update this status as soon as we have any more information.
Sorry again for the inconvenience this has caused you so far today.
