Hello,
I am experiencing a serious connectivity issue with my custom production domain:
The exact same Vercel deployment is also available at:
https://telepark-site.vercel.app
The vercel.app domain works normally and loads quickly, but tpark.ru frequently stalls during page loading or does not finish loading at all. This has been reproduced on multiple computers and browsers.
Vercel shows tpark.ru as "Valid Configuration" and connected to Production.
I performed several network tests.
The custom domain responds quickly:
HTTP: 200 TTFB: ~0.13 seconds
However, the response body then stalls.
For example:
curl --http1.1 --max-time 10 https://tpark.ru
Result:
curl: (28) Operation timed out after 10006 milliseconds with 20742 out of 136187 bytes received
HTTP: 200 TTFB: 0.132375s Total: 10.006257s Downloaded: 20742 B Speed: 2072 B/s
So the server begins responding almost immediately, but only ~20 KB of a ~136 KB response is transferred within 10 seconds.
In browser DevTools, multiple JS, CSS and image requests to tpark.ru remain in "Pending / Stalled" state.
DNS resolution and TLS connection complete successfully.
The same deployment through telepark-site.vercel.app does not exhibit this behavior.
I also completed a Vercel connectivity diagnostic against tpark.ru, testing the Vercel Edge addresses. The diagnostic log is available here:
https://gist.github.com/Komkafullaway/49592fde63d48d69049d54274ed05c90
Vercel's support assistant indicated that the logs may suggest intermediate network inspection, throttling, or a routing issue affecting this specific hostname.
Could someone from Vercel please review the connectivity trace and advise whether there is an Edge/CDN/routing issue affecting tpark.ru?
Thank you.
