I deploy several sites from the same GitHub repo. For about a year, these sites have been actively used by customers.
Since this morning, however, two of the sites stopped working out of the blue. I have started seeing errors for all functions like this one shared below.
My last deployment was several days ago, and on other sites this request works as expected.
Netlify function logs do not show any data after 9:30am CST, and the deploys were all successful. Hitting a route with a non-existing function gives a 404, but any existing function gives a 500.
I am concerned because I cannot see what would be different between these two sites, so I cannot be sure that my remaining one won’t go down as well… this would significantly disrupt our business.
Is there a reasonable explanation for this sudden disruption, and can anyone suggest a fix?
