Custom domain times out on Vercel from AS36925 MEDITELECOM in Morocco, while .vercel.app works

Help

Hello everyone,

I’m experiencing a strange connectivity issue with my custom domain:

https://www.namous.tech

The domain shows Valid Configuration in the Vercel dashboard, and the deployment URL works correctly:

https://namoustech.vercel.app

The custom domain also works from my workplace network, so the deployment, DNS configuration, SSL certificate, and domain assignment appear to be correct.

However, the custom domain times out from
My home internet connection
My PC on the home network
My phone using mobile data

The affected network is:

AS36925 MEDITELECOM
Country: Morocco

Running Vercel’s connectivity diagnostic showed that these Vercel IP addresses time out on HTTPS:

216.198.79.1
216.198.79.65
64.29.17.1
64.29.17.65

Example:

Trying 216.198.79.1:443...
Connection timed out

Trying 64.29.17.65:443...
Connection timed out

However, other IP addresses in the same Vercel ranges are reachable:+

216.198.79.129
216.198.79.193
64.29.17.129
64.29.17.193

Those reachable IPs return the expected Vercel response:

HTTP/1.1 308 Permanent Redirect
Location: https://www.namous.tech/
Server: Vercel
X-Vercel-Id: cdg1::

I also forced the custom hostname through reachable Vercel IPs:



curl.exe -4 -Iv --resolve www.namous.tech:443:216.198.79.195 https://www.namous.tech/

and:

curl.exe -4 -Iv --resolve www.namous.tech:443:64.29.17.195 https://www.namous.tech/

Both requests succeeded and returned:

HTTP/1.1 307 Temporary Redirect
Location: /fr
Server: Vercel
X-Vercel-Id: cdg1::

The full Vercel diagnostic confirms that some addresses in the range are unreachable while others work normally.

This seems like a routing, BGP, or peering issue between AS36925 MEDITELECOM and some Vercel Anycast IP addresses.

Has anyone experienced a similar issue in Morocco or with this ISP? Could someone from Vercel please help escalate this to the networking team?

I can provide the complete vercel-debug.txt report if needed.

Thank you.

I had people try it in other cities with other wifi providers and it only works on my networks and 4g/5g, and i found a temporary fix in case you’re still stuck with the problem.
