FoxNews: On Sunday, Google experienced a glitch that deleted the e-mail messages, contacts and other account information for approximately 150,000 Gmail users (0.8 percent of the total). Google has not yet released any information about what caused the problem, but said on Monday morning, "Google Mail service has already been restored for some users, and we expect a resolution for all users in the near future." The company added, "Google engineers are working to restore full access. Affected users will be temporarily unable to sign in while we repair their accounts."
Experts say the incident should serve as a reminder of the importance of backing up data.
