Urgent, getting Page Not Found error for user in New Zealand

Another customer in Australia just reported the same thing happening intermittently. No other customers in other geographies have reported the error.

I followed the instructions here: [Support Guide] I’ve deployed my site but I still see "Page not found”. I downloaded the last deploy and it indeed has an index.html file. I just redeployed the site again in case something happened with that previous deploy, but I think this is regional given that it’s only impacting certain customers.

Prior to re-deploying just now, I saw the same error showing up in my Netlify Admin snapshot (see below). Now that I’ve just redeployed the site, the error snapshot is gone when I look in my Netlify Admin.

I’m hoping there was simply something corrupt in the previous deploy, but this app has been up and running for 2.5 years of regular deploys and this has never happened until today.
