What are the steps to reproduce the issue?
We are hosting our websites in the Mumbai region across the following environments
For the past seven days, we have observed a strange behavior in the response times of our websites. Specifically, the response times are significantly slower in the northern part of India while remaining fast in the southern part.
We monitor our sites using AWS CloudWatch and confirm that our instances have sufficient resources; they are not nearing resource limits. Additionally, we use Uptime Robot to track response times and uptime. According to Uptime Robot, all our websites have 100% uptime, and the response times logged are consistently quick.
This issue appears to be regional and simultaneous. For example, when a developer in northern India cannot open the site due to slow loading, the same site loads quickly for others in southern India. At the same time, Uptime Robot logs also indicate no issues with the response times.
We have taken every possible measure on our end to investigate this issue:
Instances have sufficient resources.
Our code is clean and optimized.
We do not use load balancers and our CPU usage is way under the limit.
We have thoroughly performed all the recommended tests on our end, including:
To brief it up -
MTR and Traceroute Tests: The traffic flow appears normal, with no unusual delays or packet losses
Latency and Ping Tests: Latency times are consistently low and stable.
Server Load and Instance Metrics: Resource utilization remains well within limits, with no signs of bottlenecks or resource exhaustion.
Application Logs: No errors indicating memory exhaustion, disk full, or other system-level issues were observed in the logs.
Uptime Monitoring: Uptime Robot confirms 100% uptime, and response times are quick across all locations in its logs.
All tests conducted on our side indicate normal behavior, with no visible issues contributing to the regional performance disparity. Despite this, we continue to experience significantly slower response times for users in northern India compared to southern India.
