TeraSwitch Outage History

Teraswitch has identified a top-of-rack switch failure at our TYO1 site affecting a small subset of customers there. Services single homed to this switch are currently offline. We are working on an immediate replacement and will provide updates as more information becomes available.

The failed switch has been replaced and is being finalized for production. We will provide an update once affected services are fully restored.

We have located a network device with software issues, our team is about to reload the device. This issue affects mostly colocation customers at PIT1, but traffic from various sources may have passed through this device depending on the direction of network flow.

TeraSwitch is aware and tracking a loss of two paths from Seattle to Tokyo. This has caused much of the internet traffic to divert via public Internet Transit.

We have reached out to the vendor asking for a update. Latency from Singapore to Europe will be elevated until the outage is resolved.

Teraswitch has identified thre core backbone links that are down within the central US. This is causing US-East traffic to wrap around the world to get to US-West. Chicago/Seattle Chicago/Salt Lake City Dallas /Los Angeles We are working with our fiber vendors for a ETR.

Teraswitch is investigating reports that our console (console.tsw.io) is currently inaccessible. This issue has been identified as the result of an outage in an underlying cloud provider. We will provide an update as more information becomes available.

This issue is due to an ongoing Cloudflare outage: https://www.cloudflarestatus.com/incidents/m1xvmqf37z97. Cloudflare has implemented a fix and we are monitoring for recovery. Our API is unaffected by this issue and remains accessible.

Due to multiple undersea cable cuts, SGP1 and SGP2 is no longer operating on the Teraswitch backbone. SGP1/2 networking being unreachable for a time period was seen as network routes shifted and Internet routes adjusted.

This issue has been isolated to an ongoing Cloudflare network outage - see their incident page for more details: https://www.cloudflarestatus.com/incidents/8gmgl950y3h7

We are observing further Internet connectivity instability due to the attack and are continuing to apply mitigations. We will continue to monitor the situation until resolution and update on any further changes.

Due to a fiber cut, our backbone has diverted Amsterdam Frankfurt traffic via London. There is no impact to operations other than higher latency between cities.

Teraswitch was alerted to a loss to our path between Seattle and Tokyo. We have directed traffic to external paths. We are working with our providers to resolve this. ULL traffic between Frankfurt and Tokyo may have seen ~5 minutes of degraded connectivity.

Our sub-sea cable vendor has confirmed that repairs should be completed around 9/19/2025. At this time, Tokyo backbone traffic remains diverted.

Teraswitch is rerouting traffic due to high latency seen with multiple internet providers in Singapore.
