Multiple Sites - Network Instability Issues
Identified - The issue appears to be localized to a network transport vendor inside Frankfurt. Pass-through traffic would have been affected between cities. We believe that FRA1 and FRA2 were most impacted by this loss.

Other providers in the city were affected so we are trying to understand the full scope of the issue.

At this time network traffic is returning to normal.
Aug 25, 2025 - 22:35 UTC
Investigating - Teraswitch is investigating network instability issues affecting multiple sites. We will provide an update as more information becomes available.

FRA2 - Expedited Core Network Device Replacement
Completed - The scheduled maintenance has been completed.
Aug 21, 19:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Aug 21, 07:00 UTC
Scheduled - Teraswitch will be replacing hardware to increase capacity that has been approaching a capacity limit.

No action is necessary from customers, the expected impact is limited to a minor network traffic detour of traffic inside the FRA2 data center during the device replacement.

New York <-> London Detoured
Resolved - The subsea cable repair is done, the connections have been stable for nearly 24 hours, and traffic has been normalized across the link.

This concludes this event.
Aug 20, 18:11 UTC
Monitoring - Our sub-sea cable provider is estimating an August 20th restoration of service.

Traffic remains detoured at this time.
Aug 13, 16:50 UTC
Identified - Teraswitch has detected the loss of our subsea capacity from EWR1 to LON1.

All traffic has been diverted over other paths, but higher latency is expected over the longer path.
Aug 12, 20:19 UTC
Dublin <-> Amsterdam Intra-Market Connectivity Detoured
Resolved - The fiber has been restored.
Aug 20, 08:21 UTC
Identified - Due to a fiber cut on the Amsterdam path, Dublin (DUB1/2) traffic is diverted through London.
Aug 19, 23:00 UTC
Aug 19, 2025
Frankfurt <-> Amsterdam Intra-Market Connectivity Detoured
Resolved - The fiber fault has been cleared and traffic is normalized.
Aug 19, 18:03 UTC
Monitoring - Due to a fiber cut, all Amsterdam locations (AMS1/2/3) are diverted through London to get to Frankfurt (FRA1/2).

There is no loss to connectivity other than higher latency via the detour.
