For approximately 20 minutes, a high number of customers could not start Sauce Connect tunnels in our US-WEST region.
DNS requests between internal services during this period failed due to high network bandwidth utilization. This caused connection issues during the tunnel initialization process, which caused requests to start tunnels to fail.
The high network bandwidth utilization subsided quickly, and DNS requests began to succeed again.
Our networking team is looking at capacity to see if bottlenecks can be addressed.
