# Sanity check

After activating MarfeelCDN on a tenant, it's recommended to do the following checks validating everything works as expected.

# Browser Checks

  1. Desktop content: Check their desktop version, the content should be up to date.(New articles should appear as the tenant publishes them)
  2. Desktop images: Check the images are displaying and not distorted.
  3. QueryParam: Make a request using a query parameter (e.g.?test=1) generate a MISS in the cache layers to validate the flow to retrieve new content is OK.

TIP

The following checks only apply if the tenant is active.

  1. Mobile content: Check the Marfeel mobile version, the content should be fresh.
  2. Mobile content cache Headers: Check the cache headers are present.

# Dashboards Checks

TIP

Fastly's Dashboard access is restricted, contact the Caching System chapter if you require access.
