Oh dear - looks like Google has dropped the bomb on hundreds of thousands of Gmail accounts, wiping out years of email and chat history.
The number of affected users is reported as high as 500,000 although Google is said to be claiming that less than 0.08 per cent of users have been affected - so the number may be closer to around 150,000.
The bug means that some users are being treated as new Gmail users (complete with a friendly welcome message from the Big G) with no emails appearing in their inboxes, sent items or personal folders. There's also no Google Chat history logs on offer either.
Google has released a statement saying: "Google Mail service has already been restored for some users, and we expect a resolution for all users in the near future. Please note this time frame is an estimate and may change."
This roughly translates to - "Luckily a few seem to be okay now, but as for the rest, we haven't really got a clue when the issue will be resolved".
