"You may be using docs.google.com to access Google Drive. With the launch of the new Google Docs editors home screens, docs.google.com will redirect to the Docs home screen, where you'll find all of your Google Docs and Word files," explains Google.
Some useful URLs:
* docs.google.com, google.com/docs - Google Docs (the first URL still redirects to Drive for now)
* sheets.google.com, google.com/sheets - Google Sheets
* slides.google.com, google.com/slides - Google Slides
