Google Drive has been experiencing issues since Monday morning.
Google has restored access to its online storage service Google Drive, following a disruption which prevented users from accessing their stored files.
According to Google, the service has already been restored for some users.
The service, which takes on similar platforms from Apple and Microsoft, is aimed at allowing users to access features online, including its proprietary e-mail and documents programmes.
"We apologize for the inconvenience and thank you for your patience and continued support," the company said.
"Please rest assured that system reliability is a top priority at Google, and we are making continuous improvements to make our systems better.
"If you are still experiencing an issue, please contact us via the Google Help Center."
Google Drive, which was launched in 2012, offers free storage of up to 5GB and costs $2.49 per month or more for more space.
The platform can be used on multiple computers, including systems running on Microsoft's Windows and Apple's operating system, while stored files and documents can be shared or edited online.
