Google has stated that it is in the process of restoring data to accounts affected by a bug that wiped out email and chat history for some Gmail users. The number of user accounts wiped out by the bug has also been revised down again, this time from 0.08% of Gmail’s user base to 0.02%, or roughly 36,000 accounts. Google apologized for the mishap and the company insists that no data was lost as a result of the bug. Some user accounts have already been restored, the company said, and the remaining accounts should be back to normal soon. Google says the bug was caused by a storage software update it began deploying over the weekend. As soon as engineers were alerted of the issue, they stopped rolling out the update and reverted back to the old software.
