Hello, I am having very similar issue with two completely unrelated apps, both on a very similar stack using next.js with pages router.
Both were working just fine and prods didn’t have anything deployed in at least 1 week. Today, around 16:45 both sites started behaving weird. Like ISR pages caches were out and they were not revalidating correctly. Backend where data comes from works just fine. And since both pages are on netlify, the infra here is my first guess.
When entering a specific URL in browser the page sometimes renders correctly, but often I get just HTTP 200 with completely blank response. Headers seem fine tho, with Next.js being included there:
age:
595
cache-control:
public,max-age=0,must-revalidate
cache-status:
"Netlify Durable"; hit; fwd=stale; ttl=-535
cache-status:
"Netlify Edge"; fwd=miss
content-length:
0
content-type:
text/html; charset=utf-8

server:
Netlify
strict-transport-security:
max-age=31536000; includeSubDomains; preload
x-nextjs-cache:
STALE
x-nf-render-mode:
odb ttl=60
x-powered-by:
Next.js
What can be the issue there? I doubt it was caused by me since 1. two apps are down; 2. I didn’t do any deploys or change configuration around the apps.
