Teraswitch Status Page

Teraswitch has completed remediations to remove the bug-triggering configurations from our routers, as well as upgrading our route reflectors and adding diverse vendors on routing software. These stabilizations have proven reliable since July 30th, when we have not seen any additonal invalid packets (IS-IS LSA advertisements) inside our backbone. We expect no further impacts from this issue.

Working with our network hardware vendor, we have deployed a global change across all compute sites to improve the reliability of the connection between our Internet/backbone edge routers and our data center core networks. This change addresses the blackhole condition that caused the overnight outage. With it in place, a malformed route entering the fabric will no longer prevent traffic forwarding - sites will continue to forward via their local edge routers rather than losing reachability. We considered the previous behavior a critical flaw and have prioritized this fix accordingly. All sites, including the unaffected data centers, had this configuration change completed successfully earlier today. We continue to investigate the underlying condition that caused the default route from MIA1 to be advertised/readvertised with incorrect attributes, and will publish a full RFO once that analysis is complete. Please note: a separate, unrelated incident affecting our global traffic routing systems remains open. That work involves a distinct vendor defect and route scaling improvements, and is not connected to the outage described here.

A possible firmware/hardware bug was identified, and Teraswitch NOC elected to do a sequential software upgrade on the redundant switch pair in R102. After the reloads were complete, operations seemed to normalized. We will investigate this network switch pair further to understand the event better. Please report any outstanding issues with TYO2 to noc@teraswitch.com or to our team directly.

Our facility partner has restored power to Teraswitch's SGP2 network racks. Root cause: both redundant PDUs in each network rack were fed by power breakout boxes connected to the same overhead electrical bus bar, creating a single point of failure. Facility engineers relocated one breakout box to the correct bus, restoring power to the network equipment and eliminating the single point of failure. We expect no further impact at this time. Customer systems did not lose power at any point during this event.

Teraswitch monitoring reports that all impacts are currently resolved. Please report any further issues to our team. At EWR2, a device sitting between our data center fabric and our internet edge routers experienced a hardware fault that triggered an ASIC-level reload. After the reload, the device came back online in a degraded state and was unable to forward traffic from the data center fabric to the internet edge routers (specifically, it could not process VXLAN-routed traffic). EWR2 operates six of these core routers. Five were unaffected; however, the impaired unit failed to signal that it was incapable of forwarding traffic. Because downstream routing protocols did not detect this bad state, traffic that landed on the affected device was blackholed. Our team manually removed the router from the pool of forwarding destinations for this traffic, restoring service. We will perform all necessary follow-up steps to fully resolve the underlying issue and prevent recurrence.
