# Deferred service events
Operational or maintenance procedures applied to a cloud often lead to the
restarting of various OpenStack services and/or the calling of certain charm
hooks. Although normal, such events can be undesirable due to the service
interruptions they can cause.
The deferred service events feature provides the operator the choice of
preventing these service restarts and hook calls from occurring, which can then
be resolved at a more opportune time.
See the [Deferred service events][cdg-deferred-service-events] page in the
[OpenStack Charms Deployment Guide][cdg] for an in-depth treatment of this
feature.
