In our scenario, I found that our CloudFront delivery particularly in the Japan area is very slow for a few days. which lead our site to become slow in the time of loading the media contents .our s3 origin is in the Northern Virginia region. what might be the possible issues of this? or if something is not configured correctly?
Can anyone help me to figure this out? Is there way to identify the root cause of it? or do we rely on any log data, monitoring system in suggestion ??
Are Cache key and origin requests to Cache policy and origin request policy (recommended)changes will improve the performance? screenshots attached
