Intermittent 500/503 errors on all requests to a static site (~25% failure rate)

Hi, my site `beautiful-concha-2fa775` (custom domain `onur.mx`, site ID `5d3ef863-7cd8-4b34-a2be-d185dabdc253`) has been returning intermittent 500 and 503 errors since at least Sep 23, 2026.

- It’s a purely static site deployed via Netlify Drop (141 files). No functions, no edge functions, no redirects file.

- About 15–30% of requests fail, randomly, on any path: `/`, `/robots.txt` (60 bytes), and non-existent paths. It also happens on `beautiful-concha-2fa775.netlify.app`, so it is not a DNS or custom-domain issue.

- Control test: `www.netlify.com` and `docs.netlify.com` had 0 failures in 30 requests each, while my site failed 8 out of 30.

- The failing responses are HTTP 500 with body “Error - Request ID: …” and HTTP 503 with `cache-status: “Netlify Edge”; fwd=miss; fwd-status=503` (empty body).

- My project’s Observability panel also shows ~9–10% errors in the last hour.

- I already tried re-deploying the same zip (published 5:01 PM local time). The failure rate did not change.

- netlifystatus.com reports all systems operational.

Example failed request IDs: 01M387HHS1Q4JB9DK84A02B62N, 01M3879ZC3GJVETJZY6EEWZ99S, 01M388624K81M5SR9355GHTQ4Q.

Could someone check what is failing on the origin side for this project? Thank you.
