An apparent outage has taken out Gmail and Google Drive around the world.
The website Outage Report indicates there have been more than 1100 reports in the space of the last 20 minutes alone.
Many people have aired their frustrations on social media.
A message posted on Google's GSuite Status Dashboard said Gmail is experiencing a "service disruption."
"We're investigating reports of an issue with Gmail," it read. "We will provide more information shortly. The affected users are able to access Gmail, but are seeing error messages, high latency, and/or other unexpected behavior."
In 2016 a lengthy Gmail outage caused major problems for millions of people and businesses around the world. Unlike Wednesday's crisis, that outage began in the UK and the US and gradually spread across the world to New Zealand.
