Esri just announced a potential issue with some Python and ArcObjects workflows. So if you have or are developing your own scripts and tools using python or ArcObjects, this may cause you some problems. Here is the information Esri just sent out on this issue:

When using Python to execute geoprocessing tools and explicitly starting and stopping the edit session through the da.Editor, network inconsistencies can be introduced. The initial technical support incident reported the geoprocessing “Append” tool could introduce network inconsistencies. However, further investigation has identified that all geoprocessing editing tools called through Python, which start and stop edit sessions, have the potential to introduce network inconsistencies.

What You Need to Do
We are working hard to deliver a patch to address this issue as soon as possible. In the meantime,

• If your organization is using geoprocessing editing tools with geometric network data using Python, Esri recommends suspending use of the geoprocessing tools until the patch is available. The equivalent functionality can be safely executed in ArcMap or ArcCatalog.
• When using ArcObjects, the same issue can be encountered if the application releases all of the memory pointing to all of the classes of a geometric network that have been opened and edited in an edit session prior to the calling “StopEditing(true).” For these specific ArcObjects workflows, to avoid the risk of introducing network inconsistencies, the program should be modified to move the calls to release the memory pointing to all of the geometric network classes to after the call to stop editing.

What You Can Expect
A general patch that will work with ArcGIS 10.0 Service Pack 5, ArcGIS 10.1, 10.1 Service Pack 1, 10.2, 10.2.1, 10.2.2, and 10.3 will be made available soon. The fix will also be included in a subsequent Utilities and Telecom patch.

Esri support does have tools to help determine if you scripts have caused inconsistences in your geometric networks or not. More technical details are provided in knowledge base article ID: 44085. Please refer back to this KB article for status updates on the release of the patch.
