marine repair vessel has arrived on site as planned and has commenced operations in the vicinity of the reported fault.
Since arriving at the cable grounds, the team has been undertaking survey and inspection activities to accurately locate and assess the affected section of the cable. These operations involve detailed seabed inspection and careful positioning of specialist equipment to support the repair process. Work is ongoing, as expected. Further updates will be provided as the repair progresses. As with all submarine cable repairs, timelines remain dependent on a number of operational and environmental factors, including weather and sea conditions, and as such a confirmed restoration time frame is not yet available.

Update 2026-06-07 21:42 UTC +02:00

marine repair vessel remains on site and has continued operations over the past 24 hours. Survey activities in the vicinity of the fault have now been completed, providing the team with the necessary data to progress to the next stage of the repair.

Over the past 24 hours, our marine partner has completed a second survey of the affected cable section and successfully progressed recovery operations, including securing and handling of the cable for further assessment. Work is now moving into the next phase, which will involve detailed testing of the cable to identify and confirm the fault location, followed by preparation for repair activities. This will include the construction and testing of the initial splice once all required testing is completed. All teams remain actively engaged, and efforts are ongoing to progress the repair and restore services at the earliest opportunity.

Update 2026-06-10 14:23 UTC +02:00

Over the past 24 hours, our marine partner has progressed testing activities on the affected cable section and has successfully completed the assessment required to confirm the fault location. Following this, work has commenced on the initial splice, with construction and testing currently underway. Significant progress has been made in the splicing process, with a portion of the fibers already completed and verified through testing. The remaining fibers are being actively spliced and tested in sequence, with post-completion validation being performed to ensure quality and integrity. The repair team is continuing work on completing the splice, supported by operational testing equipment now fully available on site. Over the next 24 hours, efforts will remain focused on completing the construction and testing of the initial splice, which is a key step towards service restoration. During testing towards Holland end, an additional fault on several fibers has been identified on the cable route, located approximately 20km from the initial fault. Following completion of the current repair, the vessel will proceed to the second fault location to continue repair activities.

Update 2026-06-11 13:46 UTC +02:00

Over the past 24 hours, our marine partner has completed construction and testing of the initial splice. This phase is now complete, and the cable has laid out toward the final splice location. The buoyed end has been retrieved and is now onboard the vessel. Following this, the repair team will prepare them for the final splice. During these works, some water ingress within the Fibre tubes were observed. As part of standard repair procedures, the team is extending recovery operations to include additional cable length and conducting further testing to ensure the integrity of the repaired section before proceeding. Over the next 24 hours, efforts will focus on preparing for the final splice, and commencing its construction and testing Once the repair works at the first fault location are completed, the vessel will transit to the second fault location to continue repair activities.

Update 2026-06-12 14:56 UTC +02:00

We would like to provide you with an update on the ongoing submarine cable repair activity. Please be advised that repair operations are progressing as expected. The final splice operations, including testing, are expected to be completed within the next 24–36 hours. Once the final splice is confirmed to be satisfactory, the vessel will deploy it to the seabed and then transit (approximately 20 km east) to the second fault location to commence repair operations there. At this time, our marine repair contractor estimates that the cable system will be fully restored and traffic normalized by the 20th of June.

Update 2026-06-14 08:07 UTC +02:00

construction and testing of the final splice is progressing well, with end-to-end integrity checks being conducted from both ends of the cable. Following successful completion, the repaired cable will be deployed before the vessel transits to the second fault location to continue repair activities. Our marine repair contractor currently estimates that the cable system will be fully restored and traffic normalized by June 20th. All teams remain fully engaged and committed to restoring services at the earliest opportunity.

Update 2026-06-15 08:43 UTC +02:00
