Google suffers global outage with Gmail, YouTube and majority of services affected

Error was due to lack of storage space in authentication tools causing system to crash

Google has suffered a worldwide outage, with failures reported across the company's services, including Gmail, Google Calendar and YouTube. Beginning at about 11.50am GMT, the outages appeared to have affected the vast majority of Google's services, apart from search, which operated largely unaffected.

Despite the universal nature of the outages, the company's automated systems reported no problems for any services for the first 30 minutes, across both consumer-facing and its cloud tools for developers. At 12.25pm, the company published an update, saying We're aware of a problem ... affecting a majority of users. The affected users are unable to access [Google services]."
