UPDATE: Different services are starting to come back again, however, with some glitches, ( for instance: the address bar in Gmail not working correctly).

A Google spokesman has said: Today, “at 3.47 AM PT Google experienced an authentication system outage for approximately 45 minutes due to an internal storage quota issue. Services requiring users to log in experienced high error rates during this period. The authentication system issue was resolved at 4:32 AM PT. All services are now restored. We apologize to everyone affected, and we will conduct a thorough follow up review to ensure this problem cannot recur in the future.”

Google Services Go Down:

Today, a wide range of Google services were down for about an hour today, that hour crossed into business operation times in multiple markets, leading to a slight drop in pre-market trading for the parent company Alphabet.

Moreover, this is an alarming reminder of just how far Google reaches, and how many of our services- entertainment, productivity, and home/utility – are tied up with a single, proprietary provider.

Not only that but coincidentally, Microsoft’s Outlook is also experiencing some problems, too.

Also, there are more multiple Google services have gone down. YouTube, Gmail, Google Docs, Google Drive, Maps, Adsense and Adwords, Google Home, Google’s Chromecast, and Google Pay are all experiencing outages, with dozens, and even hundreds, of reports coming in from across Europe, the U.S, South Africa, Canada, India, countries in Central, Australia, South America, and likely more.

Additionally, downtime site indicators are showing big spikes for services dropping starting from around 11:30 AM UK time. Not only that but Google.com itself appears to still be working, albeit sluggishly. Ditto Chrome.

Moreover, some people have surmised that it’s an issue with Google Accounts – note that they were not working – or a bigger authentication issue. When everything was down, even if you tried to use Google services incognito they were not working.

So far, there are no explanations for what is going on and why all these services are down. TechCrunch tweeted that some Google services are down simultaneously in multiple countries.
