identifying one or more client resources of the plurality of client resources experiencing a functional impairment;

applying an impact analysis framework to determine the functional impairment experienced by the one or more client resources of the plurality of client resources is causally related to a maintenance operation based on a notification of the maintenance operation received from a client computer of a plurality client computers coupled to the communications network; and

directing the server to update the respective status indicators associated with the one or more client resources of the plurality of client resources whose functional impairment is causally related to the maintenance operation to reflect that the respective client resource is undergoing maintenance.

2. The system of claim 1, wherein the plurality of client resources are represented as configuration items (CIs) in a configuration management database (CMDB), and wherein the maintenance operation is defined for one or more specific CIs.

3. The system of claim 2, wherein each of the CIs comprises a CI relationship with another of the CIs, wherein at least some of the CI relationships comprise a dependency relationship, wherein the CIs and relationships constitute a service model, and wherein determining the functional impairment experienced by the one or more client resources of the plurality of client resources is causally related to the maintenance operation comprises applying a predetermined impact analysis framework.

4. The system of claim 1, wherein updating the respective status indicators associated with the one or more client resources of the plurality of client resources whose functional impairment is causally related to the maintenance operation to reflect that the respective client resource is undergoing maintenance comprises altering a color, a border, or other appearance of depiction of the respective one or more client resources of the plurality of client resources whose functional impairment is causally related to the maintenance operation.

5. The system of claim 4, wherein the updated status indicator comprises a maintenance symbol.

6. The system of claim 1, wherein the server is programmed to display at the client computer an output comprising a plurality of nodes representing the plurality of client resources, and wherein the respective status indicators comprise predefined color coding of the plurality of nodes representing the client resources whose functional impairment is causally related to the maintenance operation.

7. The system of claim 1, wherein the operations comprise updating one or more status indicators associated with one or more respective functionally impaired services that rely on underlying client resources experiencing a functional impairment causally related to the maintenance operation to indicate that the one or more respective services are functionally impaired due to the maintenance operation.

8. The system of claim 1, wherein the operations comprise updating one or more status indicators associated with one or more respective functionally impaired services that rely on underlying client resources experiencing a functional impairment causally related to the maintenance operation to indicate that the one or more respective services are not functionally impaired.

9. The system of claim 1, comprising:

a computer-driven change management component programmed to direct the server to provide a graphical client interface to receive client data comprising;

a definition of the maintenance operation;

an identification of specific client resources in the communications network associated with the maintenance operation; and

a specification of a maintenance time period applicable to the defined maintenance operation.

10. The system of claim 1, wherein the operations comprise:

storing records representing the maintenance operation;

storing records of the functional impairment experienced by the one or more client resources in response to determining the functional impairment experienced by the one or more client resources of the plurality of client resources is causally related to the maintenance operation;

utilizing the records responsive to receiving advance notification of a new maintenance operation defined for a specific client resource of the communications network, to predict instances of future functional impairment likely to occur as a consequence of the new maintenance operation; and

causing the server to provide notification to a client computer of the predicted instances of functional impairment.

11. The system of claim 1, wherein the operations comprise suspending additional status indicators in accordance with a filtering scheme received from another client computer coupled to the communications network.

12. The system of claim 1, further comprising a plurality of client computers coupled to the communications network.

13. A method, comprising:

displaying a plurality of respective status indicators for a plurality of client resources of a communications network, wherein each respective status indicator represents a functional state of a corresponding client resource of the plurality of client resources;

identifying one or more client resources of the plurality of client resources experiencing a functional impairment;

applying an impact analysis framework to determine the functional impairment experienced by the one or more client resources of the plurality of client resources is causally related to a maintenance operation based on a notification of the maintenance operation received from a client computer of a plurality client computers coupled to the communications network; and

updating the respective status indicators associated with the one or more client resources of the plurality of client resources whose functional impairment is causally related to the maintenance operation to reflect that the respective client resource is undergoing maintenance.

14. The method of claim 13, comprising updating one or more status indicators associated with one or more respective functionally impaired services that rely on underlying client resources experiencing a functional impairment causally related to the maintenance operation to indicate that the one or more respective services are functionally impaired due to the maintenance operation.

15. The method of claim 13, comprising updating one or more status indicators associated with one or more respective functionally impaired services that rely on underlying client resources experiencing a functional impairment causally related to the maintenance operation to indicate that the one or more respective services are not functionally impaired.

16. The method of claim 13, wherein the plurality of client resources are represented as configuration items (CIs) in a configuration management database (CMDB), wherein the maintenance operation is defined for one or more specific CIs, wherein each of the CIs comprises a CI relationship with another of the CIs, wherein at least some of the CI relationships comprise a dependency relationship, wherein the CIs and the CI relationships constitute a service model, and wherein determining the functional impairment experienced by the one or more client resources of the plurality of client resources is causally related to the maintenance operation comprises applying a predetermined impact analysis framework.
