This is especially chaotic for business GSuite users. Wonder if there's an offline/local cache service available for cloud-hosted systems, that would be a good middle-ground between local control and cloud-backed scale.
At the very least, if you had your Google Calendar synced to your mobile device (with the Calendar app) you can still view your meetings offline. You just can't add new ones.
This is the reality of offshoring your business infrastructure to the cloud. Yes, it can fail, and when it does you will have nothing to do but shout into the wind. You have no control over anything that could cause an outage, nor do you have any ability to fix it.
I work somewhere almost entirely integrated with GSuite for everything (Calendar, Gmail, Meet, Chat, Drive, Pixelbooks, etc) and it's a fun time right now.
