It’s not just you. Google Calendar is currently having an outage and you might not be able to view it at the moment. If you try to access it via your desktop browser, the page will return an Error 404 warning.
According to G Suite Status Dashboard, the service disruption for Calendar was reported at 10:22PM Malaysian time and Google is currently investigating the issue. They acknowledged that some users are unable to access Google Calendar.
Surprisingly, the mobile app seems to be working fine. We’ve installed a fresh copy of Google Calendar on an Android device and we are able to load and create new calendar entries.
