At approximately 13:00 UTC on October 7th, the ThousandEyes platform experienced a distributed denial of service attack which used large volumes of traffic to saturate our network connections.
While the attack lasted for about 50 minutes, the effects took about 80 minutes before the system was back into a realtime state. During that period, response times from app.thousandeyes.com were longer than normal, or connections may have failed altogether. Data uploads from all Agents to ThousandEyes collector were also affected. Once the attack ended, Agents began uploading locally cached test data.
