    1. The repair vessel continues standing by off Wainwright. Ice conditions are dynamic due to gale force west winds that are forecasted to continue through today with a potential access window later this week as conditions improve. There is confidence that the vessel will be able to continue transit to the area of operation once they clear Pt. Barrow.
    2. We recently attempted development of an alternative route to circumvent a Point Barrow passage. The forecasters review and analysis of the satellite imagery data for the NWS <1 tenth western route through the ice (see below screenshot) has determined the risk too high due to limited data and fast-moving ice. The vessel will not be pursuing this route today.
  • Recent Activity
    1. The repair vessel remains in a holding posture off Wainwright due to lingering ice conditions around Point Barrow and the fault location. See attached views.
    2. Ice continues to drift to the east and north. Much of the ice continues to fracture into smaller pieces aiding in the melt process and flushing out into the southern Beaufort Sea. Estimates are that the vessel can make the transit later this week if ice continues to abate on the current trend. The vessel will engage at the first clear and safe opportunity.
    3. No further material updates at this time.

  • Outage Notification

    Dear Quintillion Stakeholder,

    As you know, we have recently sustained a sub-sea system wide outage. We understand the importance of uninterrupted service for our priority customers, and we are working diligently to resolve the issue as quickly as possible.

    Here are the key details regarding the service outage:

    The outage is a result of an ice scouring event causing damage to our cable about 55 Km north of Oliktok Point. Our sub-sea system is currently out of service. Our dedicated team of experts is actively engaged in diagnosing and resolving the issue. They are working in coordination with our partners and undersea cable maintenance teams to restore the services at the earliest possible time. A repair vessel has been mobilized and is enroute to the area. We will be working to coordinate the timing of the vessel arrival with the ice break up around point Barrow.

    • We have engaged our marine maintenance vendor, provided data regarding the existing facilities nearby the fault location, and are planning the repair operation.
    • We are continuing to pinpoint the repair location using coherent optical time domain reflectometer equipment located at our Oliktok Point cable landing station. This will support repair planning and ultimately expedite the repair process.

    At present, we are unable to provide an exact timeline for service restoration due to the complexity of the issue. However, please be assured that we are mobilizing all available resources and applying our utmost efforts to minimize the downtime and restore services as soon as possible. The current estimate is 6-8 weeks depending on timing of ice breakup and repair requirements. See the attached maps describing the affected area.

    We understand the inconvenience this service outage may cause. We will provide regular updates (as there is substance to report) regarding the progress of the restoration efforts via email and our website.

How did the fiber cable break?

It appears the subsea cable was damaged by ice scouring—a process where moving ice, such as glaciers or icebergs, drags along the seabed floor.

When did the fiber cable break?

The break occurred on Sunday, June 11, 2023.

Where did the fiber cable break?

About 55 kilometers north of Oliktok Point in the Beaufort Sea.

When were repair ships mobilized?

On June 11, Quintillion activated a marine repair team, whose fully equipped cable repair vessel will be on standby in the Chukchi Sea, while awaiting an ice-free opening in the Beaufort Sea.

When will internet be restored?

The area in which the fiber cable broke is currently covered by sea ice and inaccessible. We expect an ice-free opening that allows repair ships to the break location will begin the first week of August.

How do you know where the fiber break occurred?

The location was determined using coherent optical time domain reflectometer equipment located at the Quintillion cable landing station facilities.

Who is on the repair team?

A team of experts—a marine repair crew; staff with experience installing and maintaining subsea fiber systems; local permitting consultants; sea ice forecasting consultants; and technical system support to evaluate the fault and complete the repair.

How do you fix a fiber cable break?

Step 1: Determine the approximate location of the break. Light pulses from a coherent time domain reflectometer device can be used to determine the location of the break. When fibers are broken, they cause light to bounce back instead of traveling to the end of the cable. Our system is equipped with this equipment and capability.

Step 2: Dispatch the repair vessels. The repair ship is loaded up with Quintillion spare cable and equipment to fix the break, and sent to the break location. Sea ice coverage information and forecasts provide guidance for safe transit—which is critical for Alaska’s harsh climates.

Step 3: Raise the subsea cable. Once on site, the repair vessel will deploy a remotely operated submersible vehicle to locate the cable break and assist with raising the cable ends up to the vessel working area.

Step 4: Replace the damaged cable section. Our team onboard the ship then repairs the cable by splicing in a replacement section of spare cable using specialized jointing equipment.

Step 5: Return cable, test, and bury again. The fixed cable is lowered back to the seafloor. Once the cable has been tested and is running at full capacity, the cable is buried.
