Shortly before 12:45pm EST, many Gmail users received error messages on their accounts, not allowing them to send or receive messages.
The search giant said it was "investigating reports of an issue" with its email service, which was partially restored by 1.30pm EST.
Google released a statement while service was being partially restored.
"We're aware that some users are experiencing an error when accessing their Gmail. We are working on a resolution and apologize for the inconvenience. Thanks for your patience."At 1.24pm the Gmail status was updated to read "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."
Many users, however, were still reporting problems accessing their account after 2pm.
Gmail, which is one of the world's most popular email services, claims more than 350 million active accounts but said overall fewer than 2 per cent of its users were affected worldwide.
But what is happening, you ask? The service is currently being upgraded to a more efficient network running the 'Openflow' open source standards. According to a Wired report claimed "hundreds of engineers" were working on the project, and that Google was even building some of its own network switches.
