Google applications including YouTube, email and Docs have suffered a rare service outage, with users unable to access many of the company's services.
The outage started shortly before noon UK time, lasting more than half an hour before being restored.
Users around the world reported problems with Gmail, Google Drive, the Android Play Store, Maps, and more.
Google's search engine, however, remained unaffected by the problems affecting its other services.
The brief outage had a significant impact on the company's millions of users, many of whom rely on Google services for basic work apps such as email and calendars.
Users of Google Docs could continue to work if they had synced documents offline, but were unable to use any online features.
It also affected Google-connected smart devices, such as its Home speakers - leading some users to complain on social media of being unable to switch off some lights in their homes
It also had a knock-on effect on other apps, with players of the smartphone game Pokémon Go, for example, reporting being unable to log in.
Despite the widespread outage, Google's service dashboard initially showed no errors - before switching to red status across all services.
"We're aware of a problem with Gmail affecting a majority of users. The affected users are unable to access Gmail," the statement said, with the word "Gmail" replaced by other services.
The cause of the problem is unclear. However, during it, users were still able to access the websites' landing pages in "incognito mode", which does not store a log of the users' browsing activity.
Google has been contacted for comment, but one spokesperson said they were unable to access their email during the outage.
Such failures in Google's systems are rare, though a problem with some servers caused difficulties for United States users in June 2019.
In that instance, the culprit was a change to server settings that was supposed to be applied to a few machines in a specific region - but was accidentally applied to many more.
