Most originate from the target sites or internal network environments.

  • Target site response itself: Sites with many images and videos take a long time to load. If it is slow even when accessed directly through a regular browser, it is a characteristic of the site.
  • In-house Web Filter and Security Program: Some security solutions may delay or block loading of external site resources. This can be resolved by whitelisting the site.
  • Temporary Access Congestion: It slows down temporarily during peak hours when users flock and then recovers.

Verification Method:

  1. Speed comparison by accessing the same site with a regular browser
  2. Check if other sites are normal
  3. Check for Exceptions in Company Web Filter and Security Programs (Administrator/Information Security Personnel)
