After analyzing one of the customer's historical cloud business failure events, ECS experienced jitter when accessing the public network. The root cause was found to be an excessive number of connections to the customer's NAT gateway, resulting in packet loss and timeouts in TCP. Based on the above analysis, we recommend that the customer increase the ECS EIP bandwidth to completely resolve the issue of jitter when accessing the public network from ECS.
