Multiple Sites - Network Instability Issues
Resolved - This incident has been resolved.
Sep 2, 15:26 UTC
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, 22:35 UTC
Investigating - Teraswitch is investigating network instability issues affecting multiple sites. We will provide an update as more information becomes available.

Frankfurt - Internet Traffic Diversion
Resolved - Our network transport provider was able to roll back their changes with no impact. At a later date they will replace the malfunctioning hardware.

Teraswitch has normalized operations in Frankfurt.
Sep 2, 15:26 UTC
Monitoring - Due to a network transport provider's routine maintenance having an issue, Teraswitch has elected to reduce risk and divert traffic from our backbone crossing through Frankfurt unnecessarily.

At this time Frankfurt traffic will be routing locally and the global backbone will only use Frankfurt if required.
