Ad Peeps Hosted uses caches to reduce very expensive
database calls and to replicate to our network of servers.
As the administrator testing the system, this is more
apparent because your testing for a particular ad right
after removal or addition.
We try to strike a good balance with caching however. Here
are some basic rules we always follow.

because they would not be cached yet.
2) Caching is not forever. In fact, our ad cache can only
live within the hour it was created. This means that if the
cache was created at 5:50 it will only live for 10 min., if
created at 5:00 it would take an hour for you to see the
3) Caching is zone, ad size specific. So if you uploaded an
ad to a new zone you would see the results right away.
