Google’s programs, such as Gmail, YouTube and maps, were temporarily unavailable to users around the world

“Something went wrong” appears on the YouTube page.

Google suffered a global crash on Monday, affecting 25 services including its video-sharing site YouTube, Google Drive, Google Play, Gmail and maps. The incident rattled many Internet users around the world, sending out social media messages asking for help. Google later announced it was fixing the problem and said its team was investigating the cause.

The web site that monitored the outage, The Downdetector, showed that Gmail, Google Drive, YouTube and maps all went down between 6:40 PM and 7:56 PM Hong Kong time on Monday, only if a web-based search function operated smoothly. The words “Something went wrong” appeared on YouTube, but users who found that they had “browsed without a trace” were able to watch the video on the site. One netizen pointed out that the smart Home system Google Home also failed for a time and the lights of the room suddenly went out. The affected service will return to normal gradually at about 8:30pm, for unknown reasons.

Google had a major outage in August and G Suite, which is primarily used by business customers, crashed globally. A similar situation occurred on YouTube last month, when computers and mobile phones were unable to stream videos and continued to be displayed in a waiting state. This year, a lot of people are working away from home, which may increase Google’s burden and cause it to crash.
