Microsoft has started alerting Docs.com users that the service will shut down on December 15. In a note posted online, the company cites Docs.com's overlap with other services, such as SlideShare and OneDrive, and a desire to streamline its offerings as the reason for the service's closure.
From Microsoft:
Following Microsoft's acquisition of LinkedIn, SlideShare has joined the Microsoft family, and represents the ideal platform for publishing your Word, PowerPoint, and PDF content with its audience of 70 million professionals, and vast content library. For custom sharing, OneDrive offers additional tools, permission settings, and security to help share and protect your data and content.
As of June 9, creating new Docs.com accounts is no longer supported. Current users will be able to keep publishing and editing content through August 1. As of December 15, "the Docs.com site and all of its content will be officially discontinued."
Microsoft is making it fairly easy to back up any content you might have stored at Docs.com. According to the instructions, you can sign into the service and enable automatic backup to OneDrive from your Docs.com profile. After that's done, all of your content on Docs.com will change to read-only mode and links to files will redirect to their locations on OneDrive. Finally, those redirected links will stop working after May 15, 2018.
Thanks for the tip, Matthew P.!
