+Capabilities
+------------
 
 VO services should offer some standard ”support” interfaces specified in
 VOSI.  In pyVO, the information obtained from these endpoints can be
 obtained from some service attributes.
 
-For availability (i.e., is the service up and running?),
-this is :py:attr:`~pyvo.dal.mixin.AvailabilityMixin.available`
-and :py:attr:`~pyvo.dal.mixin.AvailabilityMixin.up_since`
-
 Capabilities describe specific pieces of functionality (such as “this is a
 spectral search”) and further metadata (such as ”this service will never
 return more than 10000 rows”).
