No, it’s not you. Google Calendar really does appear to be down. Navigating to calendar.google.com will present you with a 404 error.
Twitter users began to complain about the outage at approximate 3:05pm BST and Gizmodo staff members have been unable to navigate to Google Calendar from either the UK, US or Canada.
This isn’t even the first outage this month. On June 2nd, Google experienced another, apparently more extreme, outage that took out Calendar, Youtube, and a number of third-party apps.
We’ve reached out to Google for more details and will update when we know more.
No doubt a coincidence, but the last Tweet sent from Google’s Gsuite Twitter account was about how the Calendar app makes scheduling simpler.
