On 14 December, all Google services including YouTube, Gmail, Google Search engine, Google Drive and few others suffered a global outage. These services were down for almost 45 minutes. During the outage, users reported that the YouTube page showed that "Something went wrong". The Gmail page also showed a message that said "Gmail is currently unable to access your Contacts. You may experience issues while this persists." When the users started reporting the issue, Google was quick to respond and acknowledge the problem. According to the company, the outage was the result of "an internal storage quota issue".
We’re all clear folks! Thanks for staying with us.
