It was a database issue not a local issue. 

Airtable fixed the issue. 

Airtable wrote to apologize. There was a back-end database issue. It would have been much better (for me at least) if their Status page indicated there was an issue, as opposed to me thinking my 6 years of work, were lost and only me and a small hand...

Yes. Back to life! Now I am backing it up! Can we rely on Airtable? This is very concerning. 

I submitted a help request through Help and Message Support. I hope they fix it and fast!
