According to the reports, Gmail, Google search engine, YouTube and Google Maps services have also been down.
Google maps if down for a long time could impact several cab services, delivery and host of other services.
Google's services went down for about an hour in a massive outage that prevented many people from watching YouTube videos, accessing their Google Docs or sending email on Gmail.
The outage also made Google Classroom temporarily unavailable, preventing many students learning remotely from accessing their classes.
"We apologize for the inconvenience and thank you for your patience and continued support," Google said in a statement.
Google said it will work toward restoring its apps for the remaining people who are still unable to access them, but the problems should largely be resolved.
