If you’ve been having issues using some Google services, you’re not alone. Several major Google services are experiencing connection issues right now.
The official G Suite Status lists Gmail and Google Drive as having issues, but users are experiencing problems with other services as well. YouTube, Hangouts, Google Play, YouTube TV (when isn’t YouTube TV down?), and various APIs have been reported as broken. Google is aware of these issues, so it shouldn’t be long until they are fixed.
