A slow website is a big turnoff for customers. But when your website's response time shoots up, should you always blame your website?
Occasionally, your end user's experience might be impacted by their internet service provider (ISP). If your website functions normally over particular geographic regions but you still have users complaining about slow response times, then their ISP may be the culprit.
In such cases, you can analyze your website response time over various ISPs used by your customers. This'll help you sort out whether response time issues are from your website or an end user's ISP.
