Major subsea network cable cut by Singapore

Notice from digital ocean team:

We’ve confirmed the degraded network performance in our first update is due to a cable cut, which occurred at approximately 18:00 UTC, April 19. This cable is located just west of Singapore and impacts the cabling system connecting 17 countries from Singapore to Europe. Users can read more about the cable here: SEA-ME-WE 5 - Submarine Networks

We continue to monitor this situation and progress of the repair. Our Engineering team will also continue to tune for performance and alternate routes where possible, until the issue is resolved.

Investigating

Due to multiple simultaneous subsea fibre cuts between Europe and Asia, we are observing degraded performance for European customers attempting to reach DigitalOcean resources hosted in our Singapore (SGP1) region, and Asian customers attempting to reach DigitalOcean resources hosted in our Amsterdam (AMS2, AMS3), London (LON1), and Frankfurt (FRA1) regions.

Engineers are attempting to improve performance where possible, but as this issue is largely out of our control we do not expect a substantial improvement in performance until one of the fibre cuts is repaired.

We apologize for any inconvenience.

The SEA-ME-WE 5 (SMW5) is a 20,000km submarine cable system connecting 17 countries through Points-of-Presence (POPs) from Singapore to the Middle East to France and Italy in Western Europe, with an initial system design capacity of 24 Tbps over 3 fiber pairs.

The SMW5 cable system has three fiber pairs between Singapore and Egypt, and four fiber pairs crossing Egypt to Europe.

The SEA-ME-WE 5 consortium consists of 19 leading telecom operators, including BSCCL, China Mobile International, China Telecom Global, China Unicom, Djibouti Telecom, Du, Myanmar Post and Telecom, Orange, Ooredoo, Telin, Saudi Telecom, SingTel, Sri Lanka Telecom, Telecom Italia Sparkle, Telecom Egypt, Telekom Malaysia, Telecom Yemen, Turk Telecom and Transworld. The SMW5 consortium signed the construction and maintenace agreement on March 7, 2014.

Alcatel-Lucent and NEC were awarded the SMW5 supply contracts, Alcatel-Lucent supplied the segments from Sri Lanka to France, while NEC supplied the Singapore to Sri Lanka segment.

The SMW5 cable system was ready for service on December 13, 2016.

In August 2019, the SMW5 cable system completed an ungrade with Ciena’s coherent 200G DWDM technology, increasing SMW5 system design capacity to 38Tbps.

And that’s why you don’t let fish run with scissors.

Right, also swimming with scissors or teeth can be hazardous.

Subsea Fiber Faults Between Europe and Asia

An update has been posted

Our Engineering team continues to work with upstream providers to resolve network connectivity issues that are occurring in multiple regions. As a result of multiple subsea fiber faults between Europe and Asia regions, the issues appear to be a direct consequence of congestion resulting in packet loss and increased latency connecting to the SGP1 region. Customers in the Asian region are having difficulty reaching DigitalOcean resources located in Amsterdam (AMS2, AMS3), London (LON1), and Frankfurt (FRA1).

We have no ETA for the upstream issues being restored but we will communicate any relevant information as we have it. We apologize for the inconvenience.

Swimming with teeth??
That would make a good movie title, though.

Subsea Fiber Faults Between Europe and Asia

Incident resolved

Our Engineering team has continued to actively monitor the situation resulting from multiple subsea fiber faults in our Singapore (SGP1) region, and Asian customers attempting to reach DigitalOcean resources hosted in our Amsterdam (AMS2, AMS3), London (LON1), and Frankfurt (FRA1) regions. Over the last five days, network connectivity to the Singapore region and Asian regions located in Amsterdam (AMS2, AMS3), London (LON1), and Frankfurt (FRA1) has not experienced any major packet loss or latency. Crews have been able to complete some cable repairs, leading to stability for the regions mentioned.

Repair of all cables from crews is still pending and may continue for multiple weeks. Given the relative stability of routes, we will now close out this incident and provide any needed updates separately.

If users experience a disruption in service or have any questions, we invite them to submit a support ticket from within their account.

Thank you for your patience and understanding throughout this incident.
