Google said access to its 'Drive' online storage service has been restored after an earlier disruption affected a "significant subset" of users.

Google revealed it was investigating reports that Google Drive was inaccessible to users at 10:17 a.m. New York time. The issue was resolved two hours later.

Google Drive, which the company began offering last year, is free up to 5 gigabytes and then costs $2.49 a month or more for additional space, depending on the amount.
