The application formerly known as Writely has been down for maintenance for the last 20 minutes or so, and has re-emerged as Google Documents & Spreadsheets. That’s right, it’s now integrated with Google Spreadsheets, and the whole thing can be accessed at http://docs.google.com. It’s been widely speculated that this integrated product will be announced tomorrow at the Office 2.0 Conference in San Francisco, and Google is competing with Zoho’s announcement of Zoho Virtual Office, also slated for tomorrow.

Update: Google has posted about the change on the Google Blog.
