Here's my paraphrasing in more straightforward fashion, since I know at least some of us would like such notices to be more to-the-point and less business-speak-ish:

Root Cause: Incorrect router configuration.

Fix Action: Revert the configuration.

Summary: Someone made the wrong settings on a router and made packets go the wrong way in parts of the US. We changed the settings back to what they were before.

Corrective Actions: We'll try to find ways to avoid doing this again. We know who did it.
