We do not check all VO services. Instead, we try to query a representative subset of all services for each VO host. If you feel that an important service is missing from this page please send us a note.

We also provide a tool for finding the status of a service using an IVO identifier: get_status_help.html.

We regularly contact service providers when a service goes down. We have recorded many of these issues here
