Affects: Traffic LINX via Global Switch Amsterdam

Our wave service provider GTT reported that there is a possible fiber cut in the sea, disrupting our services between Global Switch Amsterdam and LINX.

All traffic towards LINX is now automatically rerouted over EQX-AM7.

Their reference: 4817514

Their current updates:

The damaged cable was found.
Repair works will start during good weather conditions.
Tentative ETR is 14th January.
Next update once every 24 hours or if any new changes appear.

13-01-2020 at 4:30:
All traffic has been restored and no further interruptions are expected.
If you continue to experience any issues with your dark fiber service, please check your RAMAN amplifiers first and in case no issue observed, feel free to contact our Support team on the mentioned phone numbers at the bottom of the email.

We can confirm that all traffic carried over our DWDM network is restored since 1:17 UTC.
We are pending confirmation from the on-site engineers that the customers' equipment on site is connected and powered one.
Once that is confirmed, dark fiber customers will be contacted for confirmation on the status of their service.

NMC managed to protect several more lines. Further migration options are reviewed. Repair ship has departed last night and if the weather allows, restoration work will commence this evening.

All possible migrations were applied.
GTT will review if other migration options are possible.
Next update will be available tomorrow.

Cut is confirmed to be 121 km away from Zandvoort side.
Colocation services will be shut down in order to operate normally with the cable.
Tier 3 engineers are reviewing options for traffic migration, depending on the available capacity in the network.
The whole cable is cut, so dark fiber service migration is not possible.
Repair ship dispatch is confirmed by the contractor. Departure expected later in the evening/tomorrow, depending on the completion of the spares loading.
