Pages that have already been set to live and have since had changes made will need purged. The purge tool can be accessed from the far-right of the opening page on Sitecore (CDN purge):

To purge a page across all A Sites and B Sites (except China), enter the URL before the country code into the top box (Azure) i.e.

/de-de/features/germany/competition/

Multiple URLs can be purged at once but must be entered on a new line i.e.

/de-de/features/germany/competition/

/de-de/features/germany/trip-idea/

/es-es/features/spain/competition/

To purge a URL for the Chinese site, enter it into the bottom box (AliCloud)
