“For those Gmail users reporting missing messages, our engineers are working to restore them as soon as possible,” Google said on a webpage that provides updates on the status of its various products.
“Affected users will be temporarily unable to sign in while we repair their accounts,” the Mountain View, California-based company said.
Google said less than 0.08 percent of the users of the free Web-based email service had been affected by the problem.
Google does not release official figures for the total number of Gmail users but they are estimated to number around 200 million.
Google said Monday it expects to fully restore the Gmail accounts of users who saw their emails deleted from their inboxes over the weekend.
“We hope to have everybody back by the end of the day,” said Andrew Kovacs, a Google spokesman. “It is our expectation that we will restore all accounts.”
Google said less than 0.02 percent of the users, or about 38,000 accounts, of the free Web-based email service had been affected by the problem, fewer than previously reported.
Google had said earlier the problem affected 0.08 percent of Gmail users.
It says everything should be resolved within 12 hours.
Gmail disruptions, while rare, are seen by some industry analysts as a setback to the Mountain View, California-based Google’s efforts to promote Gmail and other Web-based services to businesses.
