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.

Monitoring
Teraswitch was attacked by a DDOS attack that specifically targeted our infrastructure and blockchain services. While our network has the capacity and mitigation ability, it took longer than expected to identify good traffic from attack traffic without further causing worse issues.
Some attack traffic sources came from very abnormal and specific locations, such as AT&T (US ISP) and a group of Brazilian ISPs. This traffic primarily landed in our Dallas data center, which overloaded select network links there on its way towards the attack targets.
We have tightened our rule sets, shifted traffic around, and are working to ensure impacts are continually mitigated.
