Yep, it’s not just you: Google Calendar appears to be down and has been since 9:47AM ET, according to Google’s App Status Dashboard.
Try going to Google Calendar now and you’ll likely be greeted with a blank page, or a server error page that tells you in a handful of languages that your meetings today are screwed and you should just go outside and escape this internet world.
We’ll keep you posted when the service returns but for now, relax. Looks like Google’s as ready for July 4th celebrations as you are.
Update: Google Calendar appears to be slowly regaining consciousness, but still down according to Google App Status. Thankfully Gmail still works so if you want to be alerted when gCal is back, you can sign up here.
