Three days after Google's Gmail first suffered an outage , some users still don't have their service back.

Gmail, a cloud -based e-mail service, had an outage that started Sunday and affected about 40,000 users, according to Google . On Monday, a Google spokesman said the service would be back up for all users by Monday night.

So far, that's not the case.

On the company's Apps Status Dashboard , Google reported at 12:51 p.m. EST today that engineers are still working on the issue and service has been restored for "some users."

"We are making good progress in restoring accounts and expect the majority of affected accounts to be reinstated today," the company wrote. "Thanks for your patience."
