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

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.

did u fix the problem? cuz im having same problem but with only orange provider i can reach my domains

nope still having the same isssue i'm waiting for orange reply

im having this problem for +3 domains. does vercel replied? and where u reached orange? so i can reach them too!

reply to #5

if you are based in morocco : https://www.orange.ma/Contactez-nous , i got nothing from vercel

Please can you confirm that the domain not reachable using only orange network 4G/5G and WIFI ,my domain is reachable when using other provider like IAM

yes im based in morocco. yes my domains are reachable from other providers like iam, its only not reachable from orange!

reply to #7

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.

if the same issue persists, try this solution : https://medium.com/@mouhssineelhaouary/how-to-fix-vercel-custom-domain-timeouts-in-specific-regions-074098d1ec20?sharedUserId=mouhssineelhaouary

Hi, I'm experiencing the exact same issue.

Environment:

Project: mre-agadir (mre-agadir-jade.vercel.app)
Custom domains: mre-a-agadir.ma and www.mre-a-agadir.ma
Apex A record: 216.198.79.1 (same IP reported in this thread)
Framework: Next.js, deployed successfully, domains show "Valid Configuration"
Plan: Hobby

What works:

mre-agadir-jade.vercel.app loads instantly, no issue
The custom domain loads perfectly when using a VPN (tested via Germany)

What doesn't work:

Both mre-a-agadir.ma and www.mre-a-agadir.ma consistently time out when accessed directly from Morocco
Confirmed across multiple ISPs (home Wi-Fi, inwi mobile data, other operators) and multiple devices (phones + computers)
Confirmed even after manually setting Google Public DNS (8.8.8.8) on a mobile device — same timeout, which rules out local ISP DNS resolver caching as the cause

This looks like a routing/peering issue between Vercel's edge network and Moroccan ISPs (Orange, Meditelecom, inwi), affecting the 216.198.79.1 apex IP specifically, rather than a DNS or application configuration problem.

Could someone from the Vercel networking team look into this? Happy to provide additional diagnostics (traceroute/mtr from within Morocco) if useful.

Thank you!

I ran the official Vercel debug script as requested. Full diagnostic output here: [ton lien Pastebin]

Summary: traceroute to 216.198.79.1 dies at hop 4, inside Meditelecom's own network (AS36925), before even reaching the public internet. This confirms the block/routing issue is happening within the ISP's network, not on Vercel's side.

hello hassan

I tested the public legacy Vercel DNS records and they restored access for the affected fixed networks:

A @ -> 76.76.21.21 CNAME www -> cname.vercel-dns-0.com

I am currently using them as a temporary workaround while waiting for Vercel to fix the routing issue affecting the newer custom-domain edge ranges.

Save your current DNS values before changing anything, since this is a workaround rather than a confirmed permanent fix.

Thank you for sharing this workaround! I was facing the exact same timeout issue with my custom domain on Orange Morocco ISP, while the site worked perfectly fine on Inwi and Maroc Telecom.

I applied the legacy DNS records as a temporary : A Record: @ -> 76.76.21.21 CNAME: www -> cname.vercel-dns-0.com

My application is now back online and fully accessible for all Orange users. I am keeping this as a temporary workaround until Vercel officially resolves the underlying routing issue for the new edge IPs in our region.
